The statistics program package from Rainbow offers five procedures with up to 100 values in each. The procedures available are mean and standard deviation; T-tests; chi-square tests, contingency tables; and regression and least square fit.
The program is menu-driven. On choosing your option, you input the data as prompted and after the last value, the S key terminates the data input stage and any further mathematical work is computed and displayed.
At this point the program drops out and to run any other option you have to type in RUN. Surely, it wouldn't take too much programming effort to return to the menu?
The instructions supplied are adequate if you understand statistics, but the less bright among us, like me, will find them difficult to follow.
The program uses no graphics at all and would appear to turn the powerful BBC B into a calculator. Graphics could be a useful addition to anyone writing such a package.
