Question

When parametric assumptions are violated or the data are in the form of ranks, what method do we use?

1) Non-parametric tests
2) Parametric tests
3) Rank tests
4) Correlation tests

Answer 1

When parametric assumptions are violated or the data are in the form of ranks, the method we use is Non-parametric tests.

Step-by-step explanation:

When parametric assumptions are violated or the data are in the form of ranks, the method we use is Non-parametric tests. Non-parametric tests do not assume a specific distribution of data and are suitable for situations where parametric assumptions are not met or when the data are in the form of ranks.
