# Multiple Regression, Chi-square test statistic

1. A multiple regression analysis includes 25 data points and 4 independent variables results in SST = 200 and SSR = 150. the multiple standard error of estimate will be?

2. A professor claimed that the proportions of grades in his classes are the same. A sample of 100 students showed the following frequencies:

grade A B C D F

frequency 18 20 28 23 11

Compute the chi-square test statistic for this problem.

#### Solution Preview

1. a multiple regression analysis includes 25 data points and 4 independent variables results in SST = 200 and SSR = 150. the multiple standard error of estimate will be?

SSE = SST-SSR= 50 =200-150

standard error of estimate= square root of (SSE/(n-k-1))= 1.5811 =square ...

#### Solution Summary

The expert calculates the value of the multiple standard error of estimate for a multiple regression and chi-square test statistic.
