We need to identify suitable statistical test for given situation
Number of treatments = 4
Observations are size of families. Number of observations can vary in all regions. No restriction on it to be same for all.
We need to check if there is any significant difference between 4 different treatment effects
One way analysis of Variance (ANOVA ) is to be used .
H0: μ1=μ2=μ3=μ4
H1: At least one of the four regions differ significantly from others.
