Testing for Normality

Remember what this test is doing!!

H0 : The data are normally distributed.

H1 : The data are not normally distributed.

Shapiro-Wilk Test

The first test we will look at is the Shapiro-Wilk test.

shapiro.test(Vec)

        Shapiro-Wilk normality test

data:  Vec
W = 0.9888, p-value = 0.5727

As the p-value is very high, we fail to reject the null hypothesis that the data set ``Vec" is normally distributed.
