What are the 2 assumptions of parametric test? Normality: Data have a normal distribution
What If Test Of Normality Is Significant? The tests mentioned above compare the scores in the sample to a normally distributed set of scores with the same mean and standard deviation; the null hypothesis is that “sample distribution is normal.” If the test is significant, the distribution is non-normal. What if the Shapiro-Wilk test is
