Arrange in correct sequential order the following statistical measures to analyse data :
I. F Ratio
II. Scheffee Post Hoc Test
III. Mean
IV. RSS, CF, TSS, \(SS_{b}\), \(SS_{w}\)
Codes :
Answer: C
The order of the statistical measures in analysing data is the mean first, then the sums of squares (RSS, CF, TSS, SSb and SSw), then the F-ratio, and then the Scheffe post hoc test, which is the code III, IV, I, II. The post hoc test is used only when the F-ratio is significant, to find which groups differ, so it comes last. The sums of squares are needed to form the F-ratio, so they come before it.
