In particular, the beaks of the finches were quite variable and seemed to play important roles in how the birds obtained food. These birds captivated Darwin. He wanted to understand the forces that allowed so many different varieties of finch to coexist successfully in such a small geographic area. His observations caused him to wonder, and his wonderment led him to ask a question that could be tested. The purpose of the question is to narrow the focus of the inquiry, to identify the problem in specific terms. The question Darwin might have asked after seeing so many different finches was something like this: What caused the diversification of finches on the Galapagos Islands?
Coming up with scientific questions isn't difficult and doesn't require training as a scientist. If you've ever been curious about something, if you've ever wanted to know what caused something to happen, then you've probably already asked a question that could launch a scientific investigation. The great thing about a question is that it yearns for an answer, and the next step in the scientific method is to suggest a possible answer in the form of a hypothesis. A hypothesis is often defined as an educated guess because it is almost always informed by what you already know about a topic. For example, if you wanted to study the air-resistance problem stated above, you might already have an intuitive sense that a car shaped like a bird would reduce air resistance more effectively than a car shaped like a box.
You could use that intuition to help formulate your hypothesis. Generally, a hypothesis is stated as an "if In making such a statement, scientists engage in deductive reasoning , which is the opposite of inductive reasoning. Deduction requires movement in logic from the general to the specific. Here's an example: If a car's body profile is related to the amount of air resistance it produces general statement , then a car designed like the body of a bird will be more aerodynamic and reduce air resistance more than a car designed like a box specific statement. Notice that there are two important qualities about a hypothesis expressed as an "if First, it is testable; an experiment could be set up to test the validity of the statement.
Second, it is falsifiable; an experiment could be devised that might reveal that such an idea is not true. If these two qualities are not met, then the question being asked cannot be addressed using the scientific method. Sign up for our Newsletter! Mobile Newsletter banner close. Descriptive studies describe the nature of the relationship between the intended variables, without looking at cause or effect. A case study covers one specific example in which something unusual has occurred. This is often done in extreme or rare cases, usually with a single subject.
Surveys are used with large groups of people who answer questions about specific subjects. Non-descriptive studies use correlational methods to predict the relationship between two or more intended variables. Verifiability means that an experiment must be replicable by another researcher. To achieve verifiability, researchers must make sure to document their methods and clearly explain how their experiment is structured and why it produces certain results.
Predictability in a scientific theory implies that the theory should enable us to make predictions about future events. The precision of these predictions is a measure of the strength of the theory. Falsifiability refers to whether a hypothesis can disproved. For a hypothesis to be falsifiable, it must be logically possible to make an observation or do a physical experiment that would show that there is no support for the hypothesis. Even when a hypothesis cannot be shown to be false, that does not necessarily mean it is not valid.
Future testing may disprove the hypothesis. This does not mean that a hypothesis has to be shown to be false, just that it can be tested. To determine whether a hypothesis is supported or not supported, psychological researchers must conduct hypothesis testing using statistics. Hypothesis testing is a type of statistics that determines the probability of a hypothesis being true or false.
Fairness implies that all data must be considered when evaluating a hypothesis. A researcher cannot pick and choose what data to keep and what to discard or focus specifically on data that support or do not support a particular hypothesis. All data must be accounted for, even if they invalidate the hypothesis. In order to ask an important question that may improve our understanding of the world, a researcher must first observe natural phenomena.
By making observations, a researcher can define a useful question. After finding a question to answer, the researcher can then make a prediction a hypothesis about what he or she thinks the answer will be. This prediction is usually a statement about the relationship between two or more variables. After making a hypothesis, the researcher will then design an experiment to test his or her hypothesis and evaluate the data gathered. These data will either support or refute the hypothesis.
Based on the conclusions drawn from the data, the researcher will then find more evidence to support the hypothesis, look for counter-evidence to further strengthen the hypothesis, revise the hypothesis and create a new experiment, or continue to incorporate the information gathered to answer the research question. The use of the scientific method is one of the main features that separates modern psychology from earlier philosophical inquiries about the mind. Many of the concepts that psychologists are interested in—such as aspects of the human mind, behavior, and emotions—are subjective and cannot be directly measured. 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.Rewrite your procedure to address Five Steps Scientific Method flaws in the original experiment.
