TV viewing habit of adopted children in relation to their biological parents and their adoptive pare
Question: TV viewing habit of adopted children in relation to their biological parents and their adoptive parents is as follows. If both biological and adoptive parents are used to produce the viewing habits of the children in multiple regression equation what percentage of the variance in the children’s scores would be accounted for? That is compute R2.
Amount of time spend watching TV| Adopted Children Y | Birth Parent X1 | Adoptive Parents X2 | |
| 2 | 0 | 1 | |
| 3 | 3 | 4 | Spx1x2=8 |
| 6 | 4 | 2 | Spx1y=15 |
| 1 | 1 | 0 | Spx2y=3 |
| 3 | 1 | 0 | |
| 0 | 2 | 3 | |
| 5 | 3 | 2 | |
| 2 | 1 | 3 | |
| 5 | 3 | 3 | |
| SSY=32 | SSx1=14 | Ssx2=16 |
