Question

Suppose you are given data from a survey showing the IQ of each person interviewed and the IQ of his or her mother. That is all the information that you have. Your boss has asked you to put together a report showing the relationship between these two variables. What could you present and why?

Answer 1

Soln

Here we should use co relation coefficient , and we can perform linear regression analysis as technique to setup a relation between person's IQ with their mother's IQ.

Here we can use scatter plot also for showing the relation between

Person's IQ to their mother's IQ.Mother's IQ can be plotted on x-axis and person's IQ on y - axis. As we can setup a relation that IQ of person's increases as their mother's IQ increases and vice versa.

By doing this analysis we can setup a equation which will clearly show the IQ relationship between person and their mother.
