24. From the above 5 diagrams, it is clear that no
clear cut views on the varieties can be
settled. Indeed, superiority amongst the
varieties is hard to judge without any suitable
criterion framed beforehand.
25. FINAL CONCLUSION:
The varieties are significantly different
4 variables namely Guanine, Sucrose, Linoleic Acid &
Phosphate are detected as responsible variables for capturing
maximum share of system variance.
We can group the 26 varieties into 5 groups(or clusters)
Canonical correlations among 7 bio-chemical groups are found
very high. So, they are governed by internal common
factor(s), which needs factor analysis (FA). Due to shortage
of time FA is not conducted.
CCA & MDS lead to adverse results regarding biochemical
groups.
From profile diagrams, indeed no clear cut conclusion on
best variety is obtained.
Correspondence Analysis on variety vs. constituents could
throw some better insight about their level wise
correspondence. Due to shortage of time such analysis could
not be done.
