For example, a pharmaceutical compound may be approved as safe because it appears safe and effective in short-term studies, while it may later be shown to be ineffective or unsafe in long-term studies. Its invocation has become routine in debates about topics that draw lay attention, from global warming to intelligent design. This stage is concerned with drawing solid, valuable conclusions from the results of the analyses phase. Once you've made your observation, you must formulate a question about what you have observed. The conclusion can be either more or less probable, based on the strength of the evidence.

Psychologists often rely instead on behavioral observations and self-reported data, which are considered by some to be illegitimate or lacking in methodological rigor. Applying the scientific method to psychology, therefore, helps to standardize the approach to understanding its very different types of information.

The scientific method allows psychological data to be replicated and confirmed in many instances, under different circumstances, and by a variety of researchers. Through replication of experiments, new generations of psychologists can reduce errors and broaden the applicability of theories. It also allows theories to be tested and validated instead of simply being conjectures that could never be verified or falsified. All of this allows psychologists to gain a stronger understanding of how the human mind works.

The scientific method is a process for experimentation that is used to explore observations and answer questions. Does this mean all scientists follow exactly this. The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century.

These papers include an Introduction, which introduces the background information and outlines the hypotheses; a Methods section, which outlines the specifics of how the experiment was conducted to test the hypothesis; a Results section, which includes the statistics that tested the hypothesis and state whether it was supported or not supported, and a Discussion and Conclusion, which state the implications of finding support for, or no support for, the hypothesis.

Writing articles and papers that adhere to the scientific method makes it easy for future researchers to repeat the study and attempt to replicate the results. Skip to main content. Researching Psychology. Search for:.

The Scientific Method Psychology and the Scientific Method: From Theory to Conclusion The scientific method offers a standardized way for psychologists to test hypotheses, build on theories, and gain knowledge about the mind. Learning Objectives Defend each step of the scientific method as necessary to psychological research.

Key Takeaways Key Points The scientific method was first outlined by Sir Francis Bacon to provide logical, rational problem solving across many scientific fields. The basic steps of the scientific method are: 1 make an observation that describes a problem, 2 create a hypothesis, 3 test the hypothesis, and 4 draw conclusions and refine the hypothesis.

The major precepts of the scientific method employed by all scientific disciplines are verifiability, predictability, falsifiability, and fairness. The application of the scientific theory to psychology took the discipline from a form of philosophy to a form of science.

What is the Scientific Method?

Critical thinking is a key component of the scientific method. Without it, you cannot use logic to come to conclusions. Your science fair project starts with a question. This might be based on an observation you have made or a particular topic that interests you.

Think what you hope to discover during your investigation, what question would you like to answer?

Your question needs to be about something you can measure and will typically start with words such as what, when, where, how or why. Talk to your science teacher and use resources such as books and the Internet to perform background research on your question.


Gathering information now will help prepare you for the next step in the Scientific Method. Using your background research and current knowledge, make an educated guess that answers your question. Your hypothesis should be a simple statement that expresses what you think will happen. Create a step by step procedure and conduct an experiment that tests your hypothesis.

Scientific method

Once you've made your observation, you must formulate a question about what you have observed. Your question should tell what it is that you are trying to discover or accomplish in your experiment. When stating your question you should be as specific as possible. Your question may be: Do plant spices inhibit bacterial growth? The hypothesis is a key component of the scientific process.

Biology and the scientific method

A hypothesis is an idea that is suggested as an explanation for a natural event, a particular experience, or a specific condition that can be tested through definable experimentation. It is important to note that a hypothesis must be testable. That means that you should be able to test your hypothesis through experimentation.

An example of a good hypothesis is: If there is a relation between listening to music and heart rate, then listening to music will cause a person's resting heart rate to either increase or decrease. Once you've developed a hypothesis, you must design and conduct an experiment that will test it. You should develop a procedure that states very clearly how you plan to conduct your experiment. It is important that you include and identify a controlled variable or dependent variable in your procedure.
