2. List the Source of Variance (SV) and their corresponding
degress of freedom (df) for each of the following ANOVA.
a. n=3, J=5
b. n=5, J=20
c. n=2, J=10
Ans:
a)number of treatments=n=3
Number of subjects in each group=5
Total number of subjects=3*5=15
df(between)=3-1=2
df(within)=15-3=12
2)number of treatments=n=5
Number of subjects in each group=20
Total number of subjects=5*20=100
df(between)=5-1=4
df(within)=100-5=95
c)number of treatments=n=2
Number of subjects in each group=10
Total number of subjects=2*10=20
df(between)=2-1=1
df(within)=20-2=18
