Question

The table below provides a list of study questions (P, Q, R) and statistical tests (i, ii, iii).

Which one of the following options correctly matches the study question to the most appropriate statistical test?

• A. P-i; Q-ii; R-iii
• B. P-i; Q-iii; R-ii
• C. P-ii; Q-i; R-iii
• D. P-ii; Q-iii; R-i

Hint:

When choosing statistical tests, always consider the type of data you have (categorical or continuous) and the type of comparison (group comparison or correlation). This will guide you to select the appropriate test.

Answer 1

The Correct Option is D

Step 1: Understand the nature of each study question and the corresponding statistical tests.
(P) "Does flower colour follow Mendelian inheritance?" is a genetic inheritance question, best analyzed using a Chi-square test to compare observed and expected frequencies of different flower colors.
(Q) "Does increased visitation by pollinators increase the number of viable fruits?" involves a comparison of means between two groups (pollinated and non-pollinated flowers), making the Student's t-test most appropriate.
(R) "Does the quantity of nectar production differ between flowers visited by pollinators compared to those that had no pollinator visitation?" involves continuous data (nectar production), making the Student's t-test appropriate here too.

Step 2: Match the correct tests to the questions.
- Option (D) correctly matches the study questions with their respective statistical tests.

Final Answer: (D)
