On this Picostat.com statistics page, you will find information about the Cars93 data set which pertains to Data from 93 Cars on Sale in the USA in 1993. The Cars93 data set is found in the MASS R package. You can load the Cars93 data set in R by issuing the following command at the console data("Cars93"). This will load the data into a variable called Cars93. If R says the Cars93 data set is not found, you can try installing the package by issuing this command install.packages("MASS") 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 Cars93 R data set. The size of this file is about 14,411 bytes.

Details

Cars were selected at random from among 1993 passenger car models that were listed in both the Consumer Reports issue and the PACE Buying Guide. Pickup trucks and Sport/Utility vehicles were eliminated due to incomplete information in the Consumer Reports source. Duplicate models (e.g., Dodge Shadow and Plymouth Sundance) were listed at most once.

Further description can be found in Lock (1993).
