QuickTTestX is a programme for calculating means, SDs and SEMs and testing the significance of differences using Student's t-test. Its main advantage over other statistical programmes is that data can be input not only as individual values (from the keyboard or by import from a text file) but also as mean Â± SD or mean Â± SEM for groups.
- For data entered from the keyboard you may indicate the decimal point either by a period (.) or by a comma (,). Further error checks for incorrectly entered data have been incorporated. The distribution format is now a .dmg file.
