Exercise 1

What educational variables are related to SAT scores Use the data if the file SAT1994.sav available on the publisher's website for this text at the address http://www.pearsonhighered.com/stern2e to answer these questions. This data set was made available by Professor Deborah Lynn Guber in the Department of Political Science at The University of Vermont. It also appears on the website at this address: http://www.amstat.org/publications/jse/jse_data_archive.html.
1. Was there a significant relation between the mean student/teacher ratio (the variable named RATIO ) and mean SAT score of states in the U.S. in 1994-1995 ( TOTAL)
2. Did states that spent more on educating each student in elementary through secondary schools have students whose mean SAT scores changed correspondingly For this analysis, determine if your results are more satisfactory when the variable Cost is transformed by taking its log to the base 10.
3. Was there a relation between the percent of students taking the SAT (the variable PERCENT ) and mean SAT score How does the result complicate interpretation of the results obtained for questions 1 and 2
