Most of you have probably read that a good strategy for memorizing words in a foreign language is to think of mnemonic keywords. ...In Exercise 16.3 you ran a test between Groups 1 and 3 combined versus Groups 2 and 4 combined. How does that test compare to testing the main effect of Location in Exercise 17.16? Is there any difference? Calculate d^ for the two main effects for the data in Exercise 17.1. (Choose two groups to compare that seem reasonable from what you understand about the design of the experiment.)
