I found that the derivation of some of the formulas was not explained. It is a good text if you plan to supplement with an array of your own materials (lectures The other 50% of the time, we'll get the right answer. Hence, our average is half the right answer (n/ (n-1)=2/1). The correction makes the standard deviation double what it should be half the same while remaining zero in the other cases. This also suggests why dividing by n is referred to as a the maximum likelihood estimator.

It is possible for a difference of little practical importance to achieve a high degree of statistical significance. It is also possible for clinically important differences to be missed because an experiment lacks the power to detect them. The little handbook of statistical practice by Gerard E.
