Statistical hypothesis testing is a formal method for deciding whether sample data provide sufficient evidence to reject a null hypothesis in favor of an alternative, using tools like p-values, significance levels, and test statistics (e.g., t-tests, chi-square tests). It is used extensively by researchers in medicine, psychology, and the social sciences to determine whether observed effects are likely real or due to chance. Proper application requires understanding concepts like Type I/II errors and statistical power.
