In Chapter 3 I presented data on the speed of deciding whether a briefly presented image was the same image as the one to its left or whether it was a reversed image. However, I worry that the trials are not independent, because I was the only subject and gave all of the responses. Use the data from the website (Ex10-25.dat) to see if response time was related to trial number. Was performance improving significantly over trials? Can we assume that there is no systematic linear trend over time? These data are available for you to download from https://www.uvm.edu/~dhowell/fundamentals8/DataFiles/Tab3-1.dat.
