Using SAS® to Create an Effect Size Resampling Distribution for a Statistical Test
... That is, the sample mean differs from the hypothesized mean by more than ½ an observed standard deviation for a medium effect size. For assessing clinical/operational significance the effect size is more meaningful than the p-value which is strongly influenced by the sample size. Note that in the on ...

... deviation was about 14 weeks. Knowing that you are a statistically-savvy person, your colleague asked you which is most likely the mean and which is the median? (a) 4.5 is the mean and 9.9 is the median. (b) 4.5 is the median and 9.9 is the mean. (c) Neither (A) nor (B) is possible given the SD of t ...

... population). Find z .0075 using the Normal table (If you have several values of z that you can use, pick the average of the extreme ones.) and use it to compute a 98.5% confidence interval. Does the mean differ significantly from 50 now? From 40? Why? Solution: Make a diagram! The diagram for z will ...

... When we have more than two groups and want to test for mutual mean difference between all the groups we usually use a form of the ANOVA method. The term is actually confusing as the test compares the means of the various groups but it does so by computing and comparing the different population varia ...
