In a cognitive psychology experiment, the researcher is interested in whether encoding condition has an effect on memory for a list of words. She recruits 12 subjects to participate in the experiment. Each subject comes to the lab twice to be tested in two different encoding conditions and their memory performance scores are listed below. The researcher would like to leave the hypothesis non-directional without predicting which encoding condition would lead to better memory, and she sets the significance level at a = .05 for a two-tailed test.
