Define “tall parents” and “short parents” according to your data. Then divide your sample into these two groups and report relevant statistics for the adult children and for parents in each group.
Galton’s article Part 1: Analysis with Galton’s original data set Galton’s work on children and parents’ height was published in: Galton, F. (1886): “Regression towards mediocrity in hereditary stature”, Journal of the Anthropological Institute, 15: 246-63. In this first part of the project you are asked to reconstruct the original data from this original article […]

Estimate the coefficient on Beauty for the multiple regression model in (b) using the three-step process in Appendix 6.3. in Stock and Watson textbook (the Frisch- Waugh theorem).
Essentials of Econometrics Empirical Exercises SW6 E6.1 Using the data set TeachingRatings described in Empirical Exercises 4.2, carry out the following exercises. (a) Run a regression of Course_Eval on Beauty. What is the estimated slope?

Discuss the difference between positive association and negative association when describing the relationship between two variables.
Correlation and Regression Discuss the difference between positive association and negative association when describing the relationship between two variables. What do we mean by the least-square criterion? Give a general description of how the least-square criterion is involve in the construction of the least-square line. Why do we say the least-squares line is the “best-fitting” […]

If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why?
Discussion: Correlation and Regression 1. If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why? 2. If we could, what other independent variables should be included in the analysis? 3. What statistic(s) would show the value of that regression in understanding BMI? […]
