In a study examining the effect of environment on development, Krech and his colleagues (1962) divided a sample of infant rats into two groups. One group was housed in a stimulus-rich environment containing ladders, platforms, tunnels, and colorful decorations. The second group was housed in stimulus-poor conditions consisting of plain gray cages. At maturity, mazelearning performance was measured for all the rats. Krech hypothesized that stimulus-rich rats would commit fewer errors than stimulus-poor rats. The following hypothetical data simulate Krech's results. The scores are the number of errors committed by each rat before it successfully solved the maze: Rich Rats: 18, 24, 27, 23, 31, 29, 20, 33, 25, 30 Poor Rats: 37, 27, 26, 31, 35, 43, 40, 36, 28, 29 Conduct a t-Test (one-tail, α = .01) for two Independent groups to see if there is a significant difference between the two groups (follow the Handout).
