QUESTION 19
The next few questions relate to this example:
For 6 months we worked with a group of 15 severely mentally handicapped individuals in an attempt to teach them self-care through imitation. For a second 6-
month period, we used physically guided practice with the same individuals. For each 6-month session, we collected ratings on the level of required assistance (high
=Dbad) for each person. The data for each individual follows (on the next page). Was the assistance significantly reduced in the second 6-month period?
