Using spss. correction from 1st Sbp systolic blood pressure question.

Answer 1

For a normal distribution,

Skewness = 0, and Kurtosis = 3

Further, the histogram of a normal distribution is symmetric.

For variable CSBP, Skewness = 1.431, kurtosis = 1.669

And from the histogram it is evident that the variable is NOT NORMAL. It is right skewed.
