Goodness‐of‐fit test for normality(e.g., Shapiro‐Wilk test)

p‐value > αpre (e.g., 10%):Do not reject H0 of normality

Parametric statistical test (e.g., two‐sample t test) 

at significance level α (e.g., 5%)

p‐value ≤ αpre (e.g., 10%):Reject H0 of normality

Non‐parametric statistical test (e.g., Mann‐Whitney U test)

at significance level α (e.g., 5%)
