WebHere's one that's not normal (it's quite right skew): If you ever happen to be using something that has neither Q-Q plots nor inverse normal cdf functions, proceed as above up to the ranking stage, then find p = r − 3 / 8 n + 1 / 4 but use the Tukey lambda approximation to the inverse normal cdf. WebPerform a normality test Choose Stat > Basic Statistics > Normality Test. The test results indicate whether you should reject or fail to reject the null hypothesis that the data come from a normally distributed population. You can do a normality test and produce a normal probability plot in the same analysis.
WebAs we can see from Graphical Tests for Normality and Symmetry, the skewness is SKEW (A4:A23) = .23 (cell D13) with standard error SQRT (6/COUNT (A4:A23)) = .55 (cell D16). Since .23 < 2*.55 = 1.10, the skewness is acceptable for a normal distribution.
