On this Picostat.com statistics page, you will find information about the students data set which pertains to Student Risk Taking . The students data set is found in the HSAUR R package. Try to load the students data set in R by issuing the following command at the console data("students"). This may load the data into a variable called students. If R says the students data set is not found, you can try installing the package by issuing this command install.packages("HSAUR") and then attempt to reload the data with library("HSAUR") followed by data("students"). 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 students 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 students R data set. The size of this file is about 389 bytes.
Student Risk Taking
Students were administered two parallel forms of a test after a random
assignment to three different treatments.
A data frame with 35 observations on the following 3 variables.
a factor with levels
the result of the first test.
the result of the second test.
The data arise from a large study of risk taking (Timm, 2002).
Students were randomly assigned to three different
treatments labelled AA, C and NC. Students were administered two
parallel forms of a test called
high. The aim is to
carry out a test of the equality of the bivariate means of each treatment
