| Abstract: | In this paper, through sample survey and statistical analysis, establishes the linear equation of the height of parents and that of their children, taking a further step in revealing the relationship between the height of parents and the height of their children, and the analysis of the result shows that the height of children from different families has a tendency to regress to the average height of the group. |
