Project #9386 - Correlation & Regression

 

Initial 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? 

Response:

You could present a Scatter plot of the data (person IQs on the y axis, mother IQs on the x axis), in order to show the type of relationship between the mother IQs and person IQs. You could also perform a linear regression analysis on Mother IQs and person IQs, so that you would have a model with which you could predict other people's IQs based on their mothers' IQs.
