WebWe test for normal distribution using the Exploration-Descriptives analysis in jamovi, looking at Shapiro-Wilk’s test, the Q-Q plot, a histogram or density plot, and skew and kurtosis z-scores. One thing to note is that for the correlation we test normality of both continuous variables. WebTo complement the graphical methods just considered for assessing residual normality, we can perform a hypothesis test in which the null hypothesis is that the errors have a normal distribution. A large p -value …
