This random number generator produces a data table with up to 10 columns and up to 2500 rows. For random integers, users must specify the data range. For data from a Normal (Gaussian) distribution, users specify mean and standard deviation.

A joke to be used in teaching about the use of randomization in experiments or about the Pearson correlation coefficient. The idea for the joke came from Lawrence Mark Lesser of The University of Texas at El Paso in 2012.
A song to be used in discussing the notation for correlation with an accompanying video that includes information about interpreting the correlation. The lyrics were written by Mary McLellan from Aledo High School in Aledo, Texas as one of several dozen songs created for her AP statistics course. The accompanying video may be found at

A song to be used in discussing how the correlation coefficient is invariant to linear transformations (or just reverses sign when values are multiplied by a negative number). The lyrics were written by Mary McLellan from Aledo High School in Aledo, Texas as one of several dozen songs created for her AP statistics course. The song may be sung to the tune of the 1980 song “Hit Me With Your Best Shot,” written by Eddie Schwartz and popularized by Pat Benatar.

A song that may be used in discussing the correlation coefficient and the interpretation of positive versus negative values and their magnitude. The lyrics were written by Mary McLellan from Aledo High School in Aledo, Texas as one of several dozen songs created for her AP statistics course. The song may be sung to the tune of Carl Perkin’s 1955 rock and roll song Blue Suede Shoes. Also, an accompanying video may be found at

A song that may be used in discussing the meaning and interpretation of R^2; the coefficient of determination. The lyrics were written by Mary McLellan from Aledo High School in Aledo, Texas as one of several dozen songs created for her AP statistics course. The song may be sung to the tune of the Christmas song Frosty the Snowman written by Walter Rollins and Steve Nelson and popularized by Gene Autry’s 1950 recording.
