To complete this Application Assignment, use the dataset anscomb.sav and SPSS to answer the following questions:
Problem 9.1:
1.Produce the scatter plot for x3 and y3. Do you think there are any outliers?
2.Calculate the correlation coefficient (r) for all the data points
3.What does the p-value in your SPSS output tell you?
4.What does r tell you about the strength of the association between x3 and y3?
5.Is either variable dependent on the other in this problem? Why or why not?
Problem 9.2:
1.Produce the scatter plot for x1 and y1. Do you think there are any outliers?
2.Fit a linear regression model for y1 against x1. Do you think this is a model with a good fit? Why?
3.Based on the results of 9.2b, is x1 a significant predictor for y1? Why?
Copy and paste (or use the File/Export option in SPSS) any required data charts or summaries into a Word document.
