Module 8 Checkpoint: Hypothesis Testing and p-values

Scenario

A test returns p = 0.03 and a colleague writes "there is a 3% chance this result is wrong".

Questions

  1. Explain what p = 0.03 actually means.
  2. Say why their sentence is not what the p-value reports.
  3. The same team ran twelve tests and reported this one. What does that change?
  4. What would you want to see alongside the p-value before acting?
  5. Write a sentence reporting this result that you would be willing to defend.

Pass Standard

You pass when you can state the p-value's definition correctly and say why twelve tests changes how one significant result should be read.
