Question

TRUE OR FALSE:

nonparametric tests are used only with data from a nominal scale

Answer 1

Non-Parametric tests:

We can apply the Non-Parametric tests when our outcome variable is not normal. Non-parametric test also called distribution-free tests.

We may use the nonparametric test on continuous, categorical, nominal, ordinal, ratio and interval scale data. However, for the continuous data, we need to check the normality condition first if normality condition not satisfied then we can apply the nonparametric test.

Hence, The given sentence is FALSE.

we can use the nonparametric tests based on nominal scale and other above mentioned scales data as well.
