Repeat the steps in Exercise 10.31 using LazStats or MYSTAT.
In Exercise 10.31
(a) Regress child height against parent height.
(b) Calculate the predicted height for children on the basis of parental height.
(c) The data file contains a variable called Quartile ranging from 1 to 4, with 1 being the lowest quartile. In SPSS use Analyze/Compare Means/One-way ANO VA to give child means corresponding to each quartile. (Make Child the dependent variable and Quartile the independent variable.) Do the same for parent means.
(d) Do the children of parents in the highest quartile have a lower mean than their parents, and vice versa for the children of parents in the lowest quartile?
(e) Draw a scatterplot with parent quartile means on the X axis and child quartile means on the Y axis and also draw a 45 degree line that would represent parents having children with the same mean height.
