Reply to The variance in the numerator of the F-ratio provides a single number that measures the differences among all of the sample means (Gravetter, 2021). The variance in the denominator of the F-ratio, like the standard error in the denominator of the t statistic, measures the mean differences that would be expected if there […]

Reply to The best way to describe a t test is “we first computed the standard error, which measures the differences between two samples means that is reasonable to expect if there is no treatment effect (Gravetter et al., 2021). For ANOVA “ we want to compare difference among two or more sample means” (Gravetter […]

Reply to It can be difficult to interpret the test outcome when there are several mean differences. An F-ratio can indicate that there is a significant difference but it does not necessarily tell where. This is where the post hoc test comes in and is necessary when rejecting the null hypothesis because it can “determine […]
