Suppose we wish to predict the global sales of video games (Global_Sales) using their North American sales (NA Sales), European sales (EU_Sales), and other sales (Other_Sales). 1. What type of analysis will you recommend? Why? 2. To visualize if there is any relationship between the global sales of video games and North American sales, as well as European sales and other sales, create scatterplots and describe what you see. 3. We wish to predict the global sales of video games using their North American sales, European sales, and other sales. What is our dependent/response variable(s) and what are the independent/predictor variable(s)? 4. Predict the global sales of video games using their North American sales, European sales, and other sales. Looking at the output (under the Analysis of Variance (ANOVA) section of the output, look at the "Regression" p-value), is this model significant? 5. Regardless of if the overall model is significant, do we see any significant predictor(s) (under Coefficients section of the output, look at each predictor's p-value)? If there is, which are significant? How do we know? 6. Now, regardless of if it is significant, interpret the effect that the slope estimate for the North American sales has on global sales of video games.
