CHOOSING A STATISTICAL TEST

CHOOSING A STATISTICAL TEST

1. Descriptive statistics don't tell us if the results could have occurred by chance, this is what statistical tests tell us

2. 3 categories of statistical tests

   • 1. is the research looking for difference or a correlation?(relationship)
     • 2. if the researcher is looking for a difference - what experimental design was being used?
       • repeated measure and matched pair - must use related test , if independent group must use 'unrelated test'
     • the hypothesis should give you a hint
