frequently missing deadlines in their classes. To gain some insight into this problem, we are going to use some of the survey data that we analyzed in Homework 2 . The data that you will need is in the HW 3 Data file included with this assignment. Your dependent variable is Question 68: On a scale from 1 to 7, how frequently do you complete course assignments and readings on time? (1-Never, 7-Always). Your potential independent variables are the remaining variables in the HW 3 Data file. Answer all of the following questions in the HW 3 Data file. Show all of your work on the designated tabs. 1. Compute correlations of all variables. Which independent variable has the highest correlation with Q68 ? 2. Find the best one-variable regression model (recall that this model will use the independent variable with the strongest correlation with the dependent variable)? Analyze the model quality. Base your answer on the R squared, model significance and independent variable significance. Regardless of quality, use this model to predict the Q68 answer of the sample student below. 3 . Find the regression model that includes the three independent variables with the strongest correlation with the dependent variable. Analyze the model quality. Base your answer on the R squared, model significance and independent variable significance. Regardless of quality, use this model to predict the Q68 answer of the sample student below.
