2. Answer the following questions (typed): (a) a. On the whole, are the two groups as similar as you expected? Explain your answer. b. Do the two groups seem to differ meaningfully on any of the variables measured? That is, did random assignment appear to work better for some variables than for others? (This question isn't as easy as it may seem. Remember the variables are scored in very different ways. For example, is a 6-point difference in depression scores similarly meaningful as a 6-point difference in age?)​
