PSYB07 Review Question

... 1. Why is n-1 rather than n used in the denominator of the formula for variance, when it is used as an inferential statistic? When can n alone be used? 2. What is the difference between interval and ratio data? What is possible to do with the latter than is inappropriate to do with the former? 3. Gi ...
