R Dataset / Package Stat2Data / FishEggs


On this Picostat.com statistics page, you will find information about the FishEggs data set which pertains to FishEggs. The FishEggs data set is found in the Stat2Data R package. You can load the FishEggs data set in R by issuing the following command at the console data("FishEggs"). This will load the data into a variable called FishEggs. If R says the FishEggs 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. 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 FishEggs R data set. The size of this file is about 591 bytes.



Fish Eggs


A dataset with 35 observations on the following 4 variables.

Age Age of the fish (in years)
PctDM Percentage of the total egg material that is solid
Month Month fish was caught: Sep=September or Nov=November
Sept Indicator with 1=September or 0=November


Researchers collected samples of female lake trout from Lake Ontario in September and November of 2002 through 2004. A goal of the study was to investigate the fertility of fish that had been stocked in the lake. One measure of the viability of fish eggs is percent dry mass(PctDM) which reflects the energy potential stored in the eggs by recording the percentage of the total egg material that is solid. Values of the PctDM for a sample of 35 lake trout (14 in September and 21 in November) are given in this dataset along with the age (in years) of the fish.
