Parametric statistics require at least interval level of measurement. It involves the use of techniques such as t-tests, ANOVA, and linear regression, which assume that the data follows a normal distribution and that the variances of the groups being compared are homogeneous. Interval level data allows for accurate mathematical operations such as addition and subtraction, which are necessary for these techniques.
