Research Design unit test

A test on this unit alone, marked as a percentage and a letter grade — for the test your class is actually sitting, rather than for May. Answer everything, then submit once: seeing the answer to question 3 before attempting question 4 makes the final percentage meaningless.

Paper 1 Paper 2 Paper 3

Each paper is built from this unit’s 29 terms and is the same for everyone, so a teacher can assign “Unit 1, Paper 3” and every student sits the identical test. Multiple choice is marked objectively; the written sections you mark yourself against the model answer and rubric.

A student writes the following in the introduction to an AP Research academic paper. "Many studies have looked at student sleep. Smith (2019) found that teenagers sleep too little. Jones (2021) found that screens hurt sleep. Lee (2022) found that later school start times help. My study will look at sleep in my school."

Explain why this passage summarizes rather than synthesizes the literature.

Explain what a gap in the literature is, and why this passage has not identified one.

Rewrite the final sentence so that it states a research question arising from an identified gap.

Explain how the gap you identified determines the method the study should use.
