On this Picostat.com statistics page, you will find information about the SAT data set which pertains to State by State SAT data. The SAT data set is found in the mosaicData R package. You can load the SAT data set in R by issuing the following command at the console data("SAT"). This will load the data into a variable called SAT. If R says the SAT data set is not found, you can try installing the package by issuing this command install.packages("mosaicData") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the SAT R data set. The size of this file is about 2,272 bytes.
