Usually these tests are computerized, but the interpretation follows the same general pattern that we have seen above. F has its own distribution. More will be said in a later lesson. As we move through the statistical concepts discussed above, we see that each successive level builds upon the previous one. Means or averages are the starting point and describe the most likely location of a value.
Standard deviations provide additional information about the distribution of values about the mean.
Knowing the mean and SD allows some inferences about the probabilities of certain events occurring. Don't let these statistics overwhelm you. The next lesson will consider statistical relationships and expand the organizer to include correlation and regression. Madelon F. Zady Madelon F.
