Data Collection & Analysis 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 33 terms and is the same for everyone, so a teacher can assign “Unit 2, Paper 2” 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 submits the following research plan. "Research question: Does using social media affect sleep? I will post a survey link in three group chats and on my own social media accounts, asking people how many hours they sleep and how much they use social media. I expect about 60 responses. I will ask, ‘Do you agree that using your phone late at night ruins your sleep?’ on a five-point scale. If the results show a relationship, I will conclude that social media use reduces sleep among teenagers." Critique this design and revise it.

Identify two problems with the research question and offer a revised version.

Evaluate the sampling plan, naming the sampling method and the specific biases it introduces.

Identify a measurement problem with the survey item and rewrite the item.

Explain why the planned conclusion is not supported by this design, and state a conclusion the design could support.
