R Dataset / Package Stat2Data / FruitFlies
On this Picostat.com statistics page, you will find information about the FruitFlies data set which pertains to FruitFlies. The FruitFlies data set is found in the Stat2Data R package. Try to load the FruitFlies data set in R by issuing the following command at the console data("FruitFlies"). This may load the data into a variable called FruitFlies. If R says the FruitFlies 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("FruitFlies"). 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 FruitFlies 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 FruitFlies R data set. The size of this file is about 3,605 bytes.
Sexual activity and lifetimes of fruit flies
A dataset with 125 observations on the following 7 variables.
Hanley and Shapiro (1994) report on a study conducted by Partridge and Farquhar (1981) about the sexual behavior of fruit flies. It was already known that increased reproduction leads to shorter life spans for female fruit flies. But the question remained whether an increase in sexual activity would also reduce the life spans of male fruit flies. The researchers designed an experiment to answer this question. They had a total of 125 male fruit flies to use and they randomly assigned each of the 125 to one of the following five groups.
The data are given as part of the data archive on the Journal of Statistics Education website and can be found on the page http://www.amstat.org/publications/jse/jse_data_archive.htm.
