Question

Quizplus · Accepted Answer

Bivariate and multivariate analyses can help identify the correlation and relationships between different items in the index. This can assist in deciding which items should be included or excluded in the index to ensure its validity and reliability. A and D are incorrect because the length and diversity of the index should be determined by its relevance and validity, not by the analysis. E is incorrect because there may be valid reasons for not performing these analyses, such as when the items are conceptually related and are expected to correlate strongly. B is incorrect because the purpose of the analysis is not to develop new items but to examine the existing ones.
