Scientific Method

526 Words3 Pages

The scientific method is a process for experimentation that is used to explore observations and answer questions. It allows psychological data to be replicated and confirmed in many instances, under different circumstances, and by a variety of researchers. (Lumen Learning). Scientists have different versions of the Scientific Method, here are the typical six parts: Purpose- What do you want to learn? Research- Find out as much as you can. Hypothesis- Try to predict the answer to the problem. Experiment- The fun part! Design a test or procedure to confirm or disprove your hypothesis. Analysis- Record what happened during the experiment. Also known as ‘data’. Conclusion- Review the data and check to see if your hypothesis was correct.

Dependent variable (the one that alters because of what we do), in this case reaction time. The dependent variable is usually the one we measure or record. The problem is always remembering which is which, simply to think of the dependent variable as the one that depends on what the researcher does! In this case reaction time (DV) depends on whether or not the participant has had a cup of coffee. Crucially an experiment allows researchers to establish a causal link between the IV and the DV. Following an experimental procedure, scientists should be certain that the alteration they have made in the IV has caused the change in the DV. Internal (or experimental) Validity Are the effects that have been caused due to the independent variable? For example, if researchers found that coffee (the I.V.) does increase speed of reaction (the D.V.), can researchers be certain that this increase is due to the coffee or could it be due to a confounding variable such as the time of day or just faster reactions of the second group. Common confounding variables include, the intelligence of participants, personality, gender, time of day, weather or the temperature. Because of these confounding variables in an experiment the researcher can take steps to minimise these, for example they could ensure that the procedure is carried out at the same time of day, in the same room, with similar temperature

Confounding factors are factors that impair the accuracy or repeatability of an experiment. In other words, it is an ability to interpret results. 7) Describe/define each of the types of experiments Controlled: An experiment that gets compared from experimental samples with control samples.

Scientific research is methodical. Created from a desire to make the unknown known, the “scientific method” was created in the 15th century based on common sense. As Barry analysis the scientific process, he says that the unknown must be made into a tool, even against one’s own ideas and beliefs. However, that concept is tenuous, so Barry uses logical situations to present the idea.

One is to “articulate the research problem and objectives”. Two is to “develop the overall research plan”. Three is to “collect the data or information”. Four is to “analyze the data or information”. Five is to “present or disseminate the findings”.

VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.

It’s a quantitative method that is specifically used in psychology researches and it examines whether two variables such as events, behaviuors, properties, and characteristics are casually related. In other words, it is a scientific and systematic approach to research, in which the researcher can manipulate and control the variables i,e an independent variable is manipulated and the dependent variable is measured and it could be called a true experiment. The main advantage of this method is that it allows us to determine and regulate cause and effect, and further it allows us to control the effects of extraneous variables. Experimental method involves some kind of measurement and a mathematical calculation is frequently involved.

The scientific method is a series of steps used by scientists everywhere around the world to work through data, hypotheses, observations and experiments. One of the most excellent examples of how scientists have used this to further progress in the human race is in the curious case of Legionnaires disease. The elusive disease first struck in 1976 at a convention in Philadelphia, causing an epidemic that would be researched for many months to come. Scientists finally came to a conclusion about the disease after following the scientific method with vigor. Understanding the problem in any situation is how you first approach solving it.

The definition of experiment is to try something to gain knowledge of the results or outcome of the experiment. Some of the ways that this has been used by Psychology were mention in the lesson such as the Monster study and different studies about attachments. I believe that dealing with the Experimental study the best term from the lecture would be the third perspective which is the cognitive perspective. The reason I chose this perspective is

They are all part of the second step in scientific method, designing and executing an experiment. Hypotheses come from theories. Theories are broader than hypotheses and may suggest many different hypotheses. The operational definition defines the variables in a hypothesis. 3.

The scientific method was able to show the differences of faith and reason by rationalism,along with inductive reasoning, pervasiveness, and how it was able to give people opportunity to experiment with things. The scientific method is a systematic procedure for collecting and analyzing evidence, which consisted of many things including: observation, measurement, and experiment, and the testing of a hypothesis. Two major keys that relate to the scientific method are rationalism and inductive reasoning. Rationalism means ideas/actions that should be based on knowledge and reason instead of faith and belief. This links to the scientific method because it agrees that you need to perform experiments, draw data, and review hypotheses in a way

I strongly agree with Poppers’ views of scientific method; firstly, deduction can provide certainty to scientific theory and allow us to accept hypothesis, law and theory as provisionally approved until it is falsified by the evidence; secondly, I believe imagination is the factor that infuses the development of science knowledge because curiosity is generally enhanced by imagination and personal perception. However, I think we should not ignore induction. In my view, induction together with deduction can be used to generate scientific knowledge. From my opinion, Science is a set of knowledge that explains factors contributing to our functional universe; scientific theories build upon past knowledge and accumulate over period of time. Scientific method is the way in which science knowledge is achieved and justified.

The Scientific Method ties in with the ideas of rationalism and inductive reasoning. It indulges our desire to gain knowledge of ourselves and the world we live in. The Scientific Method was not developed by a scientist, but a philosopher named Francis Bacon. He believed that knowledge of nature should be gained through observation and reasoning. Clearing your
