Question
The following ANOVA table is from an experiment that had a group receiving a placebo as the no treatment control, a group that received a dose of experimental compound A, another group receiving compound B while a final group received both drugs in combination. Each of the groups contained 10 subjects. The following information has been calculated but important pieces are missing.
Given the above table calculate the degrees of freedom column.
Given the above table calculate the degrees of freedom column.
Source of Variation Sum of Squares df Mean squares F-ratio P Groups (treatments) 8.804 ? 0.004 Error 10.512 ? Total 18.516 ?Explanation / Answer
here total treatments =3
therefore degree of freedom of treatments =3-1=2
for df of error =N-a =30-3 =27
mean square =SS/df
and F ratio =MS/MS error
hence below is complete table:
Source of Variation Sum of Squares df Mean squares F-ratio P Groups (treatments) 8.804 2 4.4020 11.3065068 0.004 Error 10.512 27 0.3893 Total 18.516 29 0.6385
