Given below are two statements. In the light of the statements, choose the correct answer.
- Statement I: Multivariate studies demand larger samples than univariate studies.
- Statement II: Multivariate studies do not analyse data sets involving several responses.
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 that only Statement I is true.
Explanation
★Statement I is true and Statement II is false, so the answer is that only Statement I is true.
★Multivariate analysis studies several outcome variables at the same time.
★Estimating relationships among many variables needs more data for stable results.
★So multivariate studies do indeed demand larger samples than univariate ones.
★By definition multivariate methods analyse data sets involving several responses.
★Therefore the claim that they do not analyse several responses is false.
★Univariate studies focus on one variable, while multivariate studies handle many together.
