Dr. Schram wanted to conduct an experiment on spatial intelligence using a matched-pairs design. She thought the best way to match pairs would be both to pair up people with similar generalized IQ and to make sure that the partners are tested together in the same room in the experimental condition. Is she in danger of violating any assumptions for paired-samples t tests?

Group of answer choices

No, she is not in danger of violating any assumptions for paired-samples t test.

Yes, she is in danger of violating the random sample assumption, which is a nonrobust assumption.

Yes, she is in danger of violating the independence of observations assumption, which is a nonrobust assumption.

Yes, she is in danger of violating the independence of observations assumption, but it is a robust assumption so she can proceed with the test.
