In an analysis of variance, which of the following is determined by the size of the sample variances?
SSbetween
dfbetween
SSwithin
dfwithin
| a. | SSbetween | |
| b. | dfbetween | |
| c. | SSwithin | |
| d. | dfwithin |
Solution
Answer to the question)
Sample variance is the variation observed among all the sample units. It is called Mean square within group,
This value of mean square when divided by the respective degrees of freedom gives the Sum of Square within or SSw
Thus fi the sample variance increases, the MS value increases and therefore the SSw also increases
Hence the correct answer choice is: c. SSwithin
