Hi all, it is me again. I have a question on determining if a set of data is normal at a CI = 95%. Can I use Minitab's probability plot (not probability distribution plot) under the "Graph" tab. With a CI = 95% my p-value for one set of data is 0.035 which to my understanding is not normally distributed. Another data set the p-value is 0.625 which would be above the alpha level and thus normally distributed. Is this the approperate chart to use? If so, are my conclusions correct?With regards to the normality test under the "stat->basic stat->normality test. When I do this on the first data set above, I get the same p-value = 0.035. Are both the same? If not what is the difference and which one is normally used for checking normallity?
Questions, Questions, lots of Questions...But having so much fun too!
