2. Case:1(one way anova)
• To study the effect of fertilizers A,B,C,D on yield for an year.
Here n=4 and N=10.
• H0: there Is no significant difference between the fertilizers.
• H1: there is significant difference between the fertilizers.
• Here we can see that the significant value is less than 0.05(P
value). Therefore we reject H0 and can infer that there is
significant difference between the fertilizers that is it is
having effect on the yield.
3. Case: 2(paired t-test)
• Performance score of 10 employees were recorded before
and after training. To test the training was effective using the
following score.
• Here H0: there is no effect of training.
• H1: there is effect of training.
4. Case:3 (Chi2 )
•To study the independence of attributes that is effect
on smokers with respect to age and gender.
•Here we can see that the value obtained using post
hoc test between Smokers, age, gender.
• H0: there is no relation between age and gender
with respect to smoking habit.
•H1: there is relation between age and gender with
respect to smoking.
