Regression analysis is based on several assumptions, such as linearity, normality, independence, and equal variance, which are often not fully met in practice. Therefore, it is crucial to check and address the violations of these assumptions before interpreting the regression results. Otherwise, the results may be biased, imprecise, or misleading. Moreover, regression analysis should not be the only method used to analyze data, but rather one of several approaches that complement each other to provide a comprehensive understanding of the research question at hand.
