R Dataset / Package Stat2Data / ChildSpeaks
On this Picostat.com statistics page, you will find information about the ChildSpeaks data set which pertains to ChildSpeaks. The ChildSpeaks data set is found in the Stat2Data R package. Try to load the ChildSpeaks data set in R by issuing the following command at the console data("ChildSpeaks"). This may load the data into a variable called ChildSpeaks. If R says the ChildSpeaks 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("ChildSpeaks"). 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 ChildSpeaks 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 ChildSpeaks R data set. The size of this file is about 208 bytes.
Age at first speaking and aptitude test scores
A dataset with 21 observations on the following 3 variables.
The data are from a study about whether there is a relationship between the age at which a child first speaks (in months) and his or her score on a Gesell Aptitude Test taken later in childhood.
These data were originally collected by L.M. Linde of UCLA but were first published by M.R. Mickey, O.J. Dunn, and V. Clark, "Note on the use of stepwise regression in detecting outliers," Computers and Biomedical Research, 1 (1967), pp. 105-111. The data have been used by several authors. We found them in David Moore's Basic Practice of Statistics, WH Freeman (2004)
