Math/Physic/Economic/Statistic Problem
Doing one set of t-tests for each of the two manipulations OR (2) doing two
sets of regression, one for each demographic variable. What do the results suggest when taking the 5 vs. 10% significance level?
How should the coefficients of your two explanatory variables be interpreted (i.e. what type of group comparisons do they measure)? In your opinion, do these coefficients reflect meaningful information in the present context?
Are your two explanatory variables significant and if yes, in what way?
How high is the R-squared? What does this number mean?
Provide the regression output of the same model as in (6.), but now including the interaction term.
What are now the coefficients of unbalanced and info? How does the interpretation of each coefficient change from the regression without the interaction term?
Is the interaction term significant? What is its’ interpretation?Can the coefficients of info, unbalanced, and the interaction term in the previous exercises be interpreted causally or are they merely reflecting correlations? Explain your answer.
