Question 1

What is the primary purpose of verifying assumptions in statistical testing?

  • To ensure data fits the model assumptions.
  • To increase the sample size.
  • To ignore outliers.
  • To maximize p-values.

πŸ’‘ Hint: Think about what assumptions are necessary for accurate testing.

Challenge Problems

Push your limits with challenges.

Question 1

You conducted three different tests on the same dataset. The p-value for each test was 0.04. Explain how you would apply the Bonferroni correction in this scenario.

πŸ’‘ Hint: Remember the formula for the Bonferroni correction.

Question 2

Critically evaluate a scenario in which assuming normality might lead to a potential error in results. What would be a practical approach to handle non-normal data?

πŸ’‘ Hint: Think about which tests are designed for non-normal conditions.
