What are the five characteristics of a bivariate normal distribution?
What will be an ideal response?
Ans:
1. Both the x and y, distributions of scores (marginal distributions) are normal.
2. For all values of x, there is a distribution of y values (a conditional distribution).
3. All conditional distributions are normal.
4. All conditional distributions have the same standard deviation (homoscedasticity).
5. The means of the conditional distributions (E(y|x)) of y values change linearly with x; that is, E(y|x) = ? + ?(x).
