data must be presentable , so you might want to use an increment of $ 500 for the X axis . After creating the graph , which should include the Equation and R-squared values , create a trend line . You should notice that there appears to be a close relationship between advertising spending and revenues . Your next task is to create the regression data on a separate sheet , labeled Greek Regression . As a reminder , regression analysis is located on the Data - > Data Analysis menu . Be sure to highlight the R-squared value in red , the Intercept value in blue , and the X variable 1 in green . Based on this data , and what you have learned about regression thus far , what do you think the owner should do ? Let me throw you a curve ( pun intended ). Suppose this restaurant is located near a baseball park , and it just so happens that the days the owner advertised , there were baseball games playing on those nights . Would you now have the same conclusions , or might you want to take the time to collect more data ? Statistics are not perfect , but they can provide immeasurable insight into data analysis . You just have to ask the right questions . Be sure to submit your work for this iLab to the Dropbox basket labeled Week 7 : iLab 8 .
