# Question: Explain why a chi square goodness of fit test a chi square independence test

Explain why a chi-square goodness-of-fit test, a chi-square independence test, or a chi-square homogeneity test is always right tailed.

## Answer to relevant Questions

Regarding the expected-frequency assumptions for a chisquare goodness-of-fit test, a chi-square independence test, or a chi-square homogeneity test, a. State them. b. How important are they? Refer to Table VI in Appendix A. Because of space restrictions, the numbers of degrees of freedom are not consecutive. For instance, the degrees of freedom for the numerator skips from 24 to 30. If you had only Table VI and ...Determine the following items. a. SSTR b. MSTR c. SSE d. MSE e. F Following are the notations for the three sums of squares. State the name of each sum of squares and the source of variation each sum of squares represents. a. SSE b. SSTR c. SST a. Compute SST, SSTR, and SSE by using the computing formulas given in Formula 13.1 b. Compare your results in part (a) for SSTR and SSE with those in Exercises 13.24–13.29, where you employed the defining formulas. c. ...Post your question
