Assignment:

Please answer the following 5 questions. Try not to give more than one sentence for each question.

Suppose you were told that the modal response (or the mode) for a set of survey responses to the question, "How confident are you in the government's ability to provide for public safety and security?" was "Somewhat confident." What does this mean, in words?

Suppose someone conducted a simple regression analysis of a random sample of 100 adults where the dependent variable was average income (in thousands of dollars) and the independent variable was education (in years). If the estimated regression coefficient (slope) for education is 5, what does that mean, in words?

Using the previous example, suppose the estimated intercept (or constant) is 25. What does that mean?

Suppose the p-value associated with the regression coefficient in part 2 is p = 0.01. In words, what does this mean?

Finally, suppose that we added a control variable for a respondent's age (in years) to the model from part 2. Suppose that the estimated regression coefficient for years of education is the same (5) in the multiple regression model as in the simple regression model. How does your interpretation of the regression coefficient change when we move from simple linear regression to multiple regression?
