Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is the correct order of steps for calculating and interpreting a one-way ANOVA?
A
Determine SS, Calculate df, Calculate MS, Calculate F, Compare F obtained to F critical
B
Calculate F, determine SSS, Calculate df, Compare F obtained to F critical
C
Find F and compare
D
Calculate T, calculate df, compare T obtained to T criitical
Explanation: 

Detailed explanation-1: -C. Determine SS, Calculate df, Calculate MS, Calculate F, Compare F obtained to F critical This is the correct order of steps for calculating and interpreting a one-way ANOVA.

Detailed explanation-2: -The mean squares are formed by dividing the sum of squares by the associated degrees of freedom. and the degrees of freedom for error are DFE = N-k . MSE = SSE / DFE . The test statistic, used in testing the equality of treatment means is: F = MST / MSE.

Detailed explanation-3: -F ratio formula: or. F = MSbg / MSwg The formula reads: F equals the Mean Square of the between group divided by the Mean Square of the within group. MSbg formula: MSbg = SSbg / dfbg F ratio formula: F = MSbg / MSwg F = 23.042 / 4.631. F = 4.976. Variance Source. Sum of Squares.
