 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Following information from ANOVA table is given to you. Using this information calculate the F-ratio:Degree of freedom for Between sample is 3, Total degree of freedom of Between and Within is 29, Total Sum of Squares of Between and Within sample is 57, Sum of Squares of Within sample is 35
 A 4.45 B 5.45 C 6.45 D 5.01
Explanation:

Detailed explanation-1: -An F-value is the ratio of two variances, or technically, two mean squares.

Detailed explanation-2: -The F ratio is the ratio of two mean square values. If the null hypothesis is true, you expect F to have a value close to 1.0 most of the time. A large F ratio means that the variation among group means is more than you’d expect to see by chance.

Detailed explanation-3: -F ratio. Each F ratio is computed by dividing the MS value by another MS value. The MS value for the denominator depends on the experimental design. For two-way ANOVA with no repeated measures: The denominator MS value is always the MSresidual.
