Regression and Correlation
This is the last of the trilogy (see CC/QM1 and CC/QM2). Here the study focuses on the relationship between two or more variables, but restricted to only one dependent variable. The marketer may want to know, as to how many, in the age group 25 to 40, buy his premium brand of shoes. Does it depend on income levels? If so, what bearing does the income levels have on purchases. The foundry man may want to know, how moisture content in the sand is related to blowholes. Dr. A K Rao of IIMB provides the answers. Mathematics is fi ne but the real world creates its own errors. The lesson shows how errors can be trapped. Is there a relationship between hours of sleep and examination marks? Weak as it may be, there may be a quick answer through this lesson. Link up the hours of study and the answer could be more meaningful.
