Webb13 maj 2024 · When it comes to statistical tests for normality, both Shapiro-Wilk and D’Agostino, I want to included this important caveat. With small samples, say less than 50, normality tests have little power. Webb14 juli 2024 · The Shapiro-Wilk statistic associated with the data in Figures 13.14 and 13.15 is W=.99, indicating that no significant departures from normality were detected (p=.73). As you can see, these data form a pretty straight line; which is no surprise given that we sampled them from a normal distribution! ons working from home
