In your comment state the following: When should you run post hoc tests? Why would you conduct a post hoc test? Explain why not just run three different t-Tests, one comparing groups 1 and 2, one comparing groups 1 and 3, and one comparing groups 2 and 3? Provide an example in which you would need to run a post-hoc test.

Part 2:

 State whether the example provided justifies the need to conduct a post-hoc test. In your reply explain your agreement or disagreement. 

– Imagine looking for the Ace of Clubs in a deck of cards: if you pull one card from the deck, the odds are pretty low but if you keep trying eventually you will pull the Ace.
