Hello, I have tested a distribution for normality using the Shapiro-Welch statistic. The result of this is the following:
Shapiro-Wilk normality test data: mydata W = 0.9989, p-value = 0.8791 I know that the p-value > 0.05 (for my purposes) means that the data IS normally distributed but what I am not sure is with the W value, what values tell me that the data is normally distributed. I know that my data is normally distributed, but what I want to know if how to interpret the W value, I have read that "if W is very small then the distribution is probably not normally distributed", but how "small" is "very small", and also, what happens is, say W = 0.000001 but the p-value is > my significance level (0.05)? is the hypothesis rejected? thank you!
