1. what is an F ratio and how is it calculated?

2. If SSbetween = 30, SSwithin = 40, DFbetween =3, and DFwithin = 20, then F = ?

3. If dfbetween =3, and DFwithin = 60, if alpha is set at .05, then Fcrit= ?

4. if the sample size is 30 in the mean score for group one is 5.6 means score for group 2 is 7.8 and means score for group 3 is 4.8 what is the SS between of this study?

Expert Solution

ANSWER::

1).The F-ratio is the ratio of between group variance to within group variance.

it is calculated as:-

2).given data are:-

3).given data are:-

[ in any blank cell of excel type =F.INV.RT(0.05,3,60)]

4).given data are:-

the grand mean be:-

the SS between of this study is:-

PLEASE EXPLAIN YOUR REASONING ANOVA is based on an F-ratio that is calculated as the ratio of two variance estimates, the variance between groups and the variance within groups, but enables conclusions to be made about the means of the samples involved. What is the logic of that? I.e., explain the rationale that supports the use of variance estimates.
