To use this calculator, type or paste your data in the text window. Your data values can be separated by spaces, tabs, or commas and they can be spread across several lines.
Here's what the different button do:

ComputeReports mean, standard deviation, and quartiles of the data.
Sortsorts the data
RegressionYour data must appear as data points with exactly two numbers on each line. The button opens a new window that will let you compute the least squares regression line and plot it along with a scatter plot of the data points.
tTestYour data must be presented as pairs of numbers --- observation, group --- on each line. The groups must be numbered 0 and 1. The button computes a t-test of the equality of means.
ChiSquareThe button computes ChiSquare for a test of indpendence. The data must be an rectangular array of counts with same number of counts on each line.
CopyRecords the contents of the text area in an internal buffer.
