On the test for significance, if your p-values < alpha 5%. Your decision is...
REJECT the Null (H0), REJECT the Alternate (Ha)
ACCEPT the Null (H0), ACCEPT the Alternate (Ha)
REJECT the Null (H0), ACCEPT the Alternate (Ha)
ACCEPT the Null (H0), REJECT the Alternate (Ha)
The relationship among SST, SSR, and SSE are
SST = SSR + SSE
SST = SSR - SSE
SST = 1 / (SSR + SSE)
SST = (SSR + SSE)^2
If the F-statistics < F-table, then you can conclude that
REJECT the null (H0), ACCEPT the alternate (Ha)
ACCEPT the null (H0), REJECT the alternate (Ha)
REJECT the null (H0), REJECT the alternate (Ha)
ACCPET the null (H0), ACCEPT the alternate (Ha)
The variable(s) that were OMITTED from the model
Dependent Variable
Independent Variable
Mediating Variable
Error term
The criterion for determining regression line that minimizes the sum of squared prediction errors
Least Squares Criterion
Regression Criterion
Coefficient Criterion
Correlation Criterion
