What is degree of freedom?
The maximum number of conceptually independent values, or numerical freedom of variance, in sample data is referred to as degrees of freedom. In respect to various mathematical hypothesis testing techniques, degrees of freedom are frequently discussed.
The total five groups (placebo, Drug A low, Drug A high, Drug B low, and Drug B high). Therefore, number of categories (k) is 5.
The total items in a group is 5, so the total items (n) in five groups is 25.
The numerator degree of freedom:
df=K
5-1
4
The denomination degree of freedom
df=n-K
25-5=20
F test statistic is 4.77
By the use of F table p value at the degree of freedom 4.20=0.00724
P=0.00724.
