At the heart of research lies a question. For example, consider the following scenario: you just went for a run in the park, and you feel great. Naturally, you might ask yourself "does exercise make people happy?". If you are asking a question that you don't know the answer to, research is necessary to resolve it. There are many forms that this research can take, from a literature review to performing an experiment. A technique known as statistical hypothesis testing is often used in psychology to determine a likely answer to a research question.
An Example of How to Write a Hypothesis
With hypothesis testing, the research question is formulated as two competing hypotheses: the null hypothesis and the alternative hypothesis. The null hypothesis is the default position that the effect you are looking for does not exist, and the alternative hypothesis is that your prediction is correct. The goal of hypothesis testing is to collect evidence and reject the null hypothesis if it appears unlikely to be true. In other words, if we reject the null hypothesis there is some experimental support for the alternative hypothesis (although it is important to keep in mind that we have not proved the alternative hypothesis is true).
