This key to statistical procedures is based upon one previously published by the author
(Dr. Jim Eckblad) in the Journal of College Science Teaching. In addition to the standard parametric and nonparametric statistical tests, it now includes 'bootstrap' procedures where the power of the computer can be used to estimate p-values through repeated sampling (with replacement) from the sample data; many feel this is the major advance in statistical analysis in the past three decades. |
