R Dataset / Package Stat2Data / PigFeed
On this Picostat.com statistics page, you will find information about the PigFeed data set which pertains to PigFeed. The PigFeed data set is found in the Stat2Data R package. Try to load the PigFeed data set in R by issuing the following command at the console data("PigFeed"). This may load the data into a variable called PigFeed. If R says the PigFeed data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") and then attempt to reload the data with library("Stat2Data") followed by data("PigFeed"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing PigFeed at the command-line which should display the entire dataset.
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 PigFeed R data set. The size of this file is about 193 bytes.
Effects of additives to pig feed on weight gain
A dataset with 12 observations on the following 3 variables.
A scientist in Iowa was interested in additives to standard pig chow that might increase the rate at which the pigs gained weight. Two factors of interest were vitamin B12 and antibiotics. To perform the experiment, the scientist randomly assigned 12 pigs, three to each of the diet combinations (Antibiotic only, B12 only, both, and neither).
Data are found in Statistical Methods by George W. Snedecor and William G. Cochran (1967). Ames, IA: The Iowa State University Press.
