Unit 4 - QUIZ

About This Quiz

This quiz covers the concepts from the Unit 4 readings, videos, and lessons. As a "concepts" quiz, it focuses on definitions and ideas behind the weekly topics and does not involve calculations or interpretations (we handle those elements in the practice problems and survey analysis project assignments).

Objectives

This assignment will guide your learning process to ensure you can:

• Differentiate between two-sample t-tests and paired t-tests by explaining their assumptions, conditions, and appropriate applications.
• Apply two-sample and paired t-tests to real-world data: Students will practice solving problems using the class dataset and JASP, demonstrating proficiency in applying these tests to analyze differences between groups or conditions.
• Interpret results from two-sample and paired t-tests: Students will learn to correctly interpret p-values, confidence intervals, and the results of hypothesis testing, and make appropriate conclusions based on statistical output.
• Recognize the limitations of parametric t-tests: Students will be able to identify situations where parametric t-tests are not appropriate due to violations of assumptions (e.g., normality), and understand when to use non-parametric alternatives.
• Compare and contrast parametric and non-parametric t-tests: Students will be able to discuss the strengths and limitations of both parametric and non-parametric t-tests and make informed decisions about which test to use based on data characteristics.
