scientific observation is based on the quizlet

What is research? In science, the practice of classifying organisms is called taxonomy (Taxis means arrangement and nomos mean method). Both theory and observations are essential components of scientific research. In this assignment, you will take a look at the scientific method. Positivism was typically equated with quantitative research methods such as experiments and surveys and without any explicit philosophical commitments, while antipositivism employed qualitative methods such as unstructured interviews and participant observation. Businesses and consultants research different potential solutions to remedy organizational problems such as a supply chain bottleneck or to identify customer purchase patterns. 1. If th… Physical sciences consist of disciplines such as physics (the science of physical objects), chemistry (the science of matter), and astronomy (the science of celestial objects). As such, there may be good or poor explanations, depending on the extent to which those explanations fit well with reality, and consequently, there may be good or poor theories. Performance of experimental tests of the predictions by several independentexperimenters and properly performed experiments. A scientific hypothesis is a suggested solution for an unexplained occurrence that doesn't fit into a currently accepted scientific theory. While theories may be created via reasoning, they are only authentic if they can be verified through observations. Marxism inspired social revolutions in countries such as Germany, Italy, Russia, and China, but generally failed to accomplish the social equality that it aspired. 3. If any changes are made to the measuring instruments, estimates are provided with and without the changed instrumentation to allow the readers to make a fair before-and-after comparison regarding population or employment trends. Answer to Scientific observation is based on the a. gathering of empirical evidence. Types of Observation in the Scientific Method. Theory building and theory testing are particularly difficult in the social sciences, given the imprecise nature of the theoretical concepts, inadequate tools to measure them, and the presence of many unaccounted factors that can also influence the phenomenon of interest. Any other means of knowledge acquisition, such as faith or authority cannot be considered science. It is important to understand that this knowledge may be imperfect or even quite far from the truth. Bacon’s works led to the popularization of inductive methods of scientific inquiry, the development of the “scientific method” (originally called the “Baconian method”), consisting of systematic observation, measurement, and experimentation, and may have even sowed the seeds of atheism or the rejection of theological precepts as “unobservable.”. Claims, methods and results can be more or lessobjective, and, other things being equal, the more objective, thebetter. It consists of following four steps. It attempts to “connect the dots” in research, by identifying causal factors and outcomes of the target phenomenon. Hire … Note that inductive and deductive research are two halves of the research cycle that constantly iterates between theory and observations. The scientific method allows researchers to independently and impartially test preexisting theories and prior findings, and subject them to open debate, modifications, or enhancements. Examples of something. Here, we use the newest climate model ensemble, improved observations, and a new statistical method to narrow uncertainty on estimates of past and future human-induced warming. Boy In The Water . Etymologically, the word “science” is derived from the Latin word scientia meaning knowledge. Hypothesis is created. Furthermore, there is not a single instrument or metric that can accurately measure a person’s happiness. Scientific theory definition, a coherent group of propositions formulated to explain a group of facts or phenomena in the natural world and repeatedly confirmed through experiment or observation: the scientific theory of evolution. In living beings, observation employs the senses. To call a thing objective implies that ithas a certain importance to us and that we approve of it. Methodological skills (“know-how”) are relatively standard, invariant across disciplines, and easily acquired through doctoral programs. Question options: f the hypothesis in question nobserved e 2. The theoretical level is concerned with developing abstract concepts about a natural or social phenomenon and relationships between those concepts (i.e., build “theories”), while the empirical level is concerned with testing the theoretical concepts and relationships to see how well they reflect our observations of reality, with the goal of ultimately building better theories. Observation is the active acquisition of information from a primary source. 2. Scientific research involves continually moving back and forth between theory and observations. Rationalism (not to be confused with “rationality”) views reason as the source of knowledge or justification, and suggests that the criterion of truth is not sensory but rather intellectual and deductive, often derived from a set of first principles or axioms (such as Aristotle’s “law of non-contradiction”). This is a summary of the experiment's results, and how those results match up to your hypothesis. The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century. We arrive at scientific laws or theories through a process of logic and evidence. Your parents might have told you that if you want to get great results you need to work very hard. Depending on the purpose of research, scientific research projects can be grouped into three types: exploratory, descriptive, and explanatory. Naturally, a complete researcher is one who can traverse the entire research cycle and can handle both inductive and deductive research. The participant observation method, also known as ethnographic research, is when a sociologist actually becomes a part of the group they are studying in order to collect data and understand a social phenomenon or problem.During participant observation, the researcher works to play two separate roles at the same time: subjective participant and objective observer. Comte’s ideas were expanded by Emile Durkheim in his development of sociological positivism (positivism as a foundation for social research) and Ludwig Wittgenstein in logical positivism. A theory that is specified in imprecise terms or whose concepts are not accurately measurable cannot be tested, and is therefore not scientific. Objectivity is a value. Start studying Scientific Observation CP. To some, science refers to difficult high school or college-level courses such as physics, chemistry, and biology meant only for the brightest students. Any branch of inquiry that does not allow the scientific method to test its basic laws or theories cannot be called “science.” For instance, theology (the study of religion) is not science because theological ideas (such as the presence of God) cannot be tested by independent observers using a replicable, precise, falsifiable, and parsimonious method. 3. Elegant theories are not valuable if they do not match with reality. For instance, in physics, the Newtonian Laws of Motion describe what happens when an object is in a state of rest or motion (Newton’s First Law), what force is needed to move a stationary object or stop a moving object (Newton’s Second Law), and what happens when two objects collide (Newton’s Third Law). Likewise, mountains of data are also useless until they can contribute to the construction to meaningful theories. The modern taxonomic system was developed by the Swedish botanist Carolus Linnaeus (1707-1778). Likewise, the theory of optics explains the properties of light and how it behaves in different media, electromagnetic theory explains the properties of electricity and how to generate it, quantum mechanics explains the properties of subatomic \particles, and thermodynamics explains the properties of energy and mechanical work. SURVEY . Objectivitycomes in degrees. Exploration and discovery: The early stages of a scientific investigation often rely on making observations, asking questions, and initial experimentation — essentially poking around — but the routes to and from these stages are diverse. Graduate students working on research projects for a professor may see research as collecting or analyzing data related to their project. Formulation of an hypothesis to explain the phenomena. Examples include physics, mathematics, and biology. Although instances of scientific progress have been documented over many centuries, the terms “science,” “scientists,” and the “scientific method” were coined only in the 19 th century. In physics, thehypothesis often takes the form of a causal mechanism or a mathematicalrelation. However, recognize that the scientific method operates primarily at the empirical level of research, i.e., how to make observations and analyze and interpret these observations. First, choose 1 of the following observations or questions: Option A. 1. 30 seconds . The term may also refer to any data collected during the scientific activity. 472 plays . In inductive research , the goal of a researcher is to infer theoretical concepts and patterns from observed data. However, applied sciences cannot stand on their own right, but instead relies on basic sciences for its progress. If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes a… The emphasis on verification started the separation of modern science from philosophy and metaphysics and further development of the “scientific method” as the primary means of validating scientific claims. Hypothesis Testable explanation of a scientific problem that is based on research and observation Is usually an "if, then, because" statement Must be testable through a scientific investigation Must be falsifiable Can be supported or refuted by data Example: If the chemicals react, then their mass will not change because matter cannot be created or destroyed in chemical reactions. The history of Mars observation is about the recorded history of observation of the planet Mars.Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. This chapter will examine what these terms mean. Nature of Science: Characteristics of a Scientist . There are two kinds of observations – qualitative and quantitative. A second orchard does not receive the chemical. You cannot do inductive or deductive research if you are not familiar with both the theory and data components of research. To some, science refers to difficult high school or college-level courses such as physics, chemistry, and biology meant only for the brightest students. Place the following steps of the scientific method in the correct order. Empiricism continued to clash with rationalism throughout the Middle Ages, as philosophers sought the most effective way of gaining valid knowledge. 2. This concept is called parsimony or “Occam’s razor.” Parsimony prevents scientists from pursuing overly complex or outlandish theories with endless number of concepts and relationships that may explain a little bit of everything but nothing in particular. All of the greatest scientists in the history of mankind, such as Galileo, Newton, Einstein, Neils Bohr, Adam Smith, Charles Darwin, and Herbert Simon, were master theoreticians, and they are remembered for the theories they postulated that transformed the course of science. The scientific method, as applied to social sciences, includes a variety of research approaches, tools, and techniques, such as qualitative and quantitative data, statistical analysis, experiments, field surveys, case research, and so forth. Scientific method refers to a standardized set of techniques for building scientific knowledge, such as how to make valid observations, how to interpret results, and how to generalize those results. Until recently, these constraints had limited impact, and projected warming ranges were driven primarily by model outputs. In science, observation can also involve the recording of data via the use of instruments. See more. Earth sciences consist of disciplines such as geology (the science of the earth). 1. Similarly, arts, music, literature, humanities, and law are also not considered science, even though they are creative and worthwhile endeavors in their own right. Explanatory research seeks explanations of observed phenomena, problems, or behaviors. Reasoning from observations has been important to scientific practice at least since the time of Aristotle who mentions a number of sources of observational evidence including animal dissection (Aristotle(a) 763a/30–b/15, Aristotle(b) 511b/20–25). Theories provide meaning and significance to what we observe, and observations help validate or refine existing theory or construct new theory. Most academic or doctoral research belongs to the explanation category, though some amount of exploratory and/or descriptive research may also be needed during initial phases of academic research. Scientific knowledge refers to a generalized body of laws and theories to explain a phenomenon or behavior of interest that are acquired using the scientific method. Rather than viewing these two processes in a circular relationship, as shown in Figure 1.1, perhaps they can be better viewed as a helix, with each iteration between theory and data contributing to better explanations of the phenomenon of interest and better theories. In the preceding sections, we described science as knowledge acquired through a scientific method. Overview of the Scientific Method The scientific method is a process for experimentation that is used to explore observations and answer questions. 4. This research may not lead to a very accurate understanding of the target problem, but may be worthwhile in scoping out the nature and extent of the problem and serve as a useful precursor to more in-depth research. You will design a (fictional) scientific study to answer a specific question based upon an observation. British philosopher Sir Karl Popper suggested that human knowledge is based not on unchallengeable, rock solid foundations, but rather on a set of tentative conjectures that can never be proven conclusively, but only disproven. The scientific method must satisfy four characteristics: “theory”, even though psychoanalysis may have practical utility in treating certain types of ailments. Observation and description of a phenomenon or group of phenomena. For instance, you will not find many disagreements among natural scientists on the speed of light or the speed of the earth around the sun, but you will find numerous disagreements among social scientists on how to solve a social problem such as reduce global terrorism or rescue an economy from a recession. Scientific knowledge is built as people come up with hypotheses and theories, repeatedly test them against observations of the natural world, and continue to refine those explanations based on new ideas and observations. Examples include understanding the reasons behind adolescent crime or gang violence, with the goal of prescribing strategies to overcome such societal ailments. Observe something and ask questions about a natural phenomenon (scientific observation) 2. Kant’s ideas led to the development of German idealism , which inspired later development of interpretive techniques such as phenomenology, hermeneutics, and critical social theory. For instance, if the citizens of a country are generally dissatisfied with governmental policies regarding during an economic recession, exploratory research may be directed at measuring the extent of citizens’ dissatisfaction, understanding how such dissatisfaction is manifested, such as the frequency of public protests, and the presumed causes of such dissatisfaction, such as ineffective government policies in dealing with inflation, interest rates, unemployment, or higher taxes. The natural sciences are very precise, accurate, deterministic, and independent of the person m aking the scientific observations. Critical research (also called critical theory) propounded by Max Horkheimer and Jurgen Habermas in the 20 th century, retains similar ideas of critiquing and resolving social inequality, and adds that people can and should consciously act to change their social and economic circumstances, although their ability to do so is constrained by various forms of social, cultural and political domination. Precision: Theoretical concepts, which are often hard to measure, must be defined with such precision that others can use those definitions to measure those concepts and test that theory. Tags: Question 12 . 4. Prior to this time, science was viewed as a part of philosophy, and coexisted with other branches of philosophy such as logic, metaphysics, ethics, and aesthetics, although the boundaries between some of these branches were blurred. A scientific process or scientific method requires observations of nature and formulating and testing the hypothesis. Laws are observed patterns of phenomena or behaviors, while theories are systematic explanations of the underlying phenomenon or behavior. The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations that is dedicated to providing the world with objective, scientific information relevant to understanding the scientific basis of the risk of human-induced climate change, its natural, political, and economic impacts and risks, and possible response options. Depending on a researcher’s training and interest, scientific inquiry may take one of two possible forms: inductive or deductive. http://scholarcommons.usf.edu/oa_textbooks/3/, CC BY-NC-SA: Attribution-NonCommercial-ShareAlike. Hence, inductive research is also called theory-building research, and deductive research is theory-testing research. However, theoretical skills (“know-what”) is considerably harder to master, requires years of observation and reflection, and are tacit skills that cannot be “taught” but rather learned though experience. In other words, scientific observation of the universe would not even be possible if the laws of the universe had been incompatible with the development of sentient life. What is science? Examples of descriptive research are tabulation of demographic statistics by the United States Census Bureau or employment statistics by the Bureau of Labor, who use the same or similar instruments for estimating employment by sector or population growth by ethnicity over multiple employment surveys or censuses. For instance, if you measure a person’s happiness using a hypothetical instrument, you may find that the same person is more happy or less happy (or sad) on different days and sometimes, at different times on the same day. In the earliest days of human inquiry, knowledge was usually recognized in terms of theological precepts based on faith. While … Sometimes, there may not be a single universal truth, but rather an equilibrium of “multiple truths.” We must understand that the theories, upon which scientific knowledge is based, are only explanations of a particular phenomenon, as suggested by a scientist. Erstwhile communist economies like the Soviet Union and China eventually moved toward more capitalistic economies characterized by profit-maximizing private enterprises. The roots of this thought lie in Das Capital , written by German philosophers Karl Marx and Friedrich Engels, which critiqued capitalistic societies as being social inequitable and inefficient, and recommended resolving this inequity through class conflict and proletarian revolutions. Conducting scientific research, therefore, requires two sets of skills – theoretical and methodological – needed to operate in the theoretical and empirical levels respectively. It is also very difficult to refute theories that do not work. Learn vocabulary, terms, and more with flashcards, games, and other study tools. A scientist testing the affects of a chemical on apple yeild sprays an orchard with the chemical. 3. Introduction. estimate the nature, quality, ability or significance of. Scientific Observation A method of testing hypothesis by unobtrusively watching and recording participants' behavior in a systematic and objective manner, either in a laboratory or natural setting. The next stage of the Scientific Method is known as the "hypothesis." Unlike theories in the natural sciences, social science theories are rarely perfect, which provides numerous opportunities for researchers to improve those theories or build their own alternative theories. 1. The goal of scientific research is to discover laws and postulate theories that can explain natural or social phenomena, or in other words, build scientific knowledge. Experiment is performed and results are consistent with prediction. For instance, relying solely on observations for making inferences and ignoring theory is not considered valid scientific research. In science, theories are important, but theories alone may not be enough to prove or disprove a hypothesis. Those who can do it well are also the most prized scientists in their disciplines. Which of the following is least likely be categorized as “science”? Many describe it as an "educated guess," based on prior knowledge and observation. Exploratory research is often conducted in new areas of inquiry, where the goals of the research are: (1) to scope out the magnitude or extent of a particular phenomenon, problem, or behavior, (2) to generate some initial ideas (or “hunches”) about that phenomenon, or (3) to test the feasibility of undertaking a more extensive study regarding that phenomenon. Both basic and applied sciences are required for human development. The same as an observation. Ungraded . Using the scientific method allows one to take a systematic approach to formulating a hypothesis and arriving at … Based on this premise, Bacon emphasized knowledge acquisition as an empirical activity (rather than as a reasoning activity), and developed empiricism as an influential branch of philosophy. Other descriptive research may include chronicling ethnographic reports of gang activities among adolescent youth in urban populations, the persistence or evolution of religious, cultural, or ethnic practices in select communities, and the role of technologies such as Twitter and instant messaging in the spread of democracy movements in Middle Eastern countries. The progress of science is marked by our progression over time from poorer theories to better theories, through better observations using more accurate instruments and more informed logical reasoning. Which of the following statements is an inference of the picture? Observation is essential to the process of science, but it is only half the picture. Critical research attempts to uncover and critique the restrictive and alienating conditions of the status quo by analyzing the oppositions, conflicts and contradictions in contemporary society, and seeks to eliminate the causes of alienation and domination (i.e., emancipate the oppressed class).
