Textbook Title: Statistics at Square One
This free etextbook online presents a number of new techniques in statistics, such as stem and leaf plots, box whisker plots, data transformation, the χ² test for trend and t test with unequal variance. The textbook includes a chapter on survival analysis, with the Kaplan-Meier survival curve and the log rank test, as these are now in common use. The textbook assumes that the reader will not want to master a complicated statistical program, but assumes that the reader has available a simple scientific calculator.
