How do I decide which statistical test to use?

When it comes to deciding which statistical test to use, there are a few key factors to consider. First and foremost, you need to clearly define the research question or hypothesis you want to test. This will help determine whether you need to compare means, proportions, correlations, or something else. Next, consider the type of data you have and its distribution. For example, if you have categorical variables, you may consider using chi-square tests, while continuous variables may require t-tests or ANOVA. Additionally, the sample size and study design may influence your choice of statistical test. It is also essential to understand the assumptions associated with each test and assess whether they are met. Consulting textbooks, statistical software, or seeking advice from a statistician or data analyst can further assist in making an informed decision on the appropriate statistical test to use.
