Creating Realistic Data Sets with Specified Properties via Simulation
Goldman, Robert N.; McKenzie, John D. Jr.
Teaching Statistics: An International Journal for Teachers, v31 n1 p7-11 Jan 2009
We explain how to simulate both univariate and bivariate raw data sets having specified values for common summary statistics. The first example illustrates how to "construct" a data set having prescribed values for the mean and the standard deviation--for a one-sample t test with a specified outcome. The second shows how to create a bivariate data set with a specified correlation coefficient.
