A cognitive psychologist wanted to examine what kinds of learning techniques are more/less effective for brain surgeons to memorize neuroanatomy. The research obtained a sample of 13 surgeons in their third year of medical school. Each surgeon was asked to use three different learning techniques (didactic instruction, rote memorization with ashcards, and discussion groups). The surgeons were also graded on their performance after each learning technique. Grades on the surgeon performance could range from 1 to 100. Below are the results. Descriptive Statistics Std.
