R Dataset / Package robustbase / coleman
On this Picostat.com statistics page, you will find information about the coleman data set which pertains to Coleman Data Set. The coleman data set is found in the robustbase R package. Try to load the coleman data set in R by issuing the following command at the console data("coleman"). This may load the data into a variable called coleman. If R says the coleman data set is not found, you can try installing the package by issuing this command install.packages("robustbase") and then attempt to reload the data with library("robustbase") followed by data("coleman"). 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 coleman 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 coleman R data set. The size of this file is about 698 bytes.
Coleman Data Set
Contains information on 20 Schools from the Mid-Atlantic and New England States, drawn from a population studied by Coleman et al. (1966). Mosteller and Tukey (1977) analyze this sample consisting of measurements on six different variables, one of which will be treated as a responce.
A data frame with 20 observations on the following 6 variables.
