Question

1.)

Interpret the results and explain your interpretation (5 pts)

Is the overall regression model significant?

How much of the variance in effort is explained by the regression model?

If the overall model is interpretable (significant), which variables are significant and what is the direction of their relationship with the DV?

Explanation / Answer

The values R-squared and adjusted R-squared for the model are extremely poor. The p-values for the coefficient estimates are also not significant. Hence , the overall model is not significant.

The model explains 2.3% of the variance in effort.

None of the variables are significant. X11 has a positive relationship with the DV while X8 and D12 have a negative relationship.
