When data meet certain assumptions, parametric statistics can be used. First, the data must be continuous, which includes data that represent ratio and interval scales of measurement. Ordinal or discrete data that have a large number of possible scores can be analyzed with parametric statistics as well. Other assumptions are that the sample size is adequate, the population distribution is normal, and the group variances are equal.
