Test 1 study guide

The information below provides an overview of the first test: what it covers, how to prepare, the format and due date, and relevant datasets.

Scope

The first test covers the following topics:

• data semantics
• descriptive statistics
• point and interval estimation for a population mean

The relevant learning outcomes on which you’ll be assessed are:

• [L2] distinguish between observational studies and experiments and understand the limitations (practical and consequential) of each
• [L3] summarize data using graphical and numerical techniques
• [L4] construct and interpret confidence intervals for means

In terms of class material, this covers all lectures in weeks 1 and 2 and textbook sections 1.1-1.5, 3.3.1-3.3.3, and 4.1-4.2.

Preparation

I recommend reviewing the following materials to prepare:

1. Lecture notes and slides
2. Textbook sections
3. Homework assignments
4. Lab activities

You may also wish to try a few example problems from the relevant textbook sections.

Format

The first test will be a take-home assessment that you may complete anytime on Friday, April 18. In format it will be similar to your homework assignments, insofar as you will have:

• a Posit Cloud project to complete
• a Microsoft Forms quiz to submit

The test is open-book and open-note, but you must complete it individually. No discussion or collaboration with other students in the class is allowed; failure to adhere to this policy will result in loss of credit.

To complete the test on time, you must submit the MS Forms quiz by 11:59pm Friday, April 18. In accord with class policy, there is a one-hour grace period on the submission deadline; otherwise, extensions must be arranged in advance.
