Shapiro-Wilk test
Cards in this deck (7)
- 1What does the Shapiro-Wilk test, test for?Normality
- 2What does a Shapiro-Wilk test give you?- Test statistic
- p-value - 3How do you report a Shapiro-Wilk test?W(df) = test stat, p = .xxx
- 4What are the degrees of freedom for a Shapiro-Wilk?Equal to N (sample size)
- 5What are the hypotheses for a Shapiro-Wilk test?H0 (null) = Data is normally distributed
H1 (alternative) = Data is not normally distributed - 6What does a p value of ≥ .05 mean?If p ≥ .05, we accept H0
The test stat is NOT significant, the assumption of normality is upheld, data is normally distributed - 7What does a p value of < .05 mean?If p < .05, we reject H0
The test stat is significant, the assumption of normality has been violated, data is NOT normally distributed
