The Normality Analysis function in SPSS enables users to test whether their data follows a normal distribution, a fundamental assumption in many statistical tests. SPSS provides various methods, such as histograms, Q-Q plots, the Shapiro-Wilk test, and the Kolmogorov-Smirnov test, to evaluate normality. Checking for normality helps determine the appropriate statistical methods for analysis, ensuring the validity of hypothesis testing. Understanding normality is crucial for making accurate inferences and selecting the right statistical techniques.
