Researchers do null hypothesis testing to determine whether a sample relationship (such as a correlation or difference between groups) represents a real relationship in the population, or if it could have happened by chance. This is typically done by setting up a null hypothesis, which assumes that there is no true relationship in the population, and then testing whether the sample data supports or contradicts this null hypothesis. By doing so, researchers are able to draw conclusions about the population based on the sample data.
