Why is it possible to get a negative value for t but not for F?
What will be an ideal response?
A t-test examines the difference between a sample mean and population mean in standard deviation units. Thus, the sample mean can be smaller or larger than the population mean, enabling positive and negative values. An F-test, on the other hand, examines the ratio of two variability statistics. Since variability cannot be negative, the F statistic must always be positive.
