Though the northernmost islands experience a bit of rain, September is largely dry, warm and sunny throughout the islands. High season in Hawaii doesn't start till mid-December, so September is still off-season for the Hawaii tourism industry and deals abound.
T-tests and analysis of variance (ANOVA) are widely used statistical methods to compare group means. For example, the independent sample t-test enables you to compare annual personal income between rural and urban areas and examine the difference in the grade point average (GPA) between male and female students.
The next output that we should discuss is that labeled as âType 3 Tests of Fixed Effectsâ. This is the standard output we would get if we werenât specifying âmethod = type 3â. This is the method SAS uses to calculate the ANOVA (if this is confusing don't worry, we haven't talked about this yet). These are the Fcalculated and p-value for the test of any variables that are specified in the model statement. Note that the F and p-values are identical to that which we see in the full ANOVA table.
