Helps novices compute statistical t-tests

In depth

A closer look at ttest

This program was designed to enable total statistical novices to carry out and interpret either of two statistical tests for comparing the average scores across two groups or conditions. The program guides the user through the specification of the experimental design and the entry of the data, and it then carries out the standard statistical tests for answering questions like 'Are these two sets of numerical scores different to a statistically reliable extent?' (For the technically informed, these tests often called paired and unpaired t-tests, or t-tests for 'within-subjects' and 'between-subjects' designs. Finally, the program gives some English-language hints about how the results should be interpreted. The program was written for use by students who have little or no previous training in statistics but need to analyze data collected in a laboratory class for their student writeups. The program has been used successfully by first- and second-year university students, but it should also be useable by high-school students with minimal coaching from a teacher.
