Given below are two statements. Statement I: Parametric tests cannot be applied to ordinal or nominal scale data. Statement II: Parametric tests do not suppose any particular distribution and the consequential assumptions. In the light of the above statements, choose the correct answer from the options given below.
- Statement I: Parametric tests cannot be applied to ordinal or nominal scale data.
- Statement II: Parametric tests do not suppose any particular distribution and the consequential assumptions.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false ✓ Correct
DStatement I is false but Statement II is true
Correct answer: (C) Statement I is true but Statement II is false — Statement I is true and Statement II is false, so the answer is Statement I is true but Statement II is false.
Explanation
★Statement I is true and Statement II is false, so the answer is Statement I is true but Statement II is false.
★Parametric tests work on continuous, quantitative data.
★Ordinal and nominal data are qualitative, so parametric tests are not applied to them, making statement I true.
★Parametric tests do assume a particular distribution, usually the normal distribution.
★They rest on the assumptions that follow from that distribution.
★So saying they suppose no distribution is wrong, making statement II false.
★Therefore statement I is true while statement II is false.
