Question
Which study below is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means)? Choose the best answer.
CASE A: A man wants to determine whether early exposure to sunlight will affect plant growth. He samples 12 different pairs of flowers (12 different kinds of flowers; two of each kind) to run his experiment. One flower of each pair is exposed to sunlight for 2 days while the other flower of each pair remains in the shade. At the end of the 2 days, the flowers are measured for growth. The scores are normally distributed and based on an interval scale of measurement. Assume all test assumptions have been met.
CASE B: A man wants to determine whether early exposure to sunlight will affect plant growth. He samples 12 different flowers to run his experiment. The 12 flowers are divided into two groups based on the family of plant they come from. The group of flowers from family A is exposed to sunlight for 2 days while the flowers from family B remain in the shade. At the end of the 2 days, the flowers are measured for growth. The scores are normally distributed and based on an interval scale of measurement. Assume all test assumptions have been met.
Neither CASE A nor CASE B is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
Both CASE A and CASE B are appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
Only CASE B is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
Only CASE A is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
a.Neither CASE A nor CASE B is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
b.Both CASE A and CASE B are appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
c.Only CASE B is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
d.Only CASE A is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means).
Explanation / Answer
Ans:
Option d is correct.
Only CASE A is appropriate for the t-test for Matched Pairs (AKA: Dependent; Repeated; Correlated Means),as subjects are meausred pairwise,so dependent samples.
