A study was conducted to investigate the effect of management training on the decisionmaking

Question

abilities of supervisors in a large corporation. Sixteen supervisors were selected
and eight were randomly chosen to receive managerial training. Four trained and
four untrained supervisors were then randomly selected to function in a situation in
which a standard problem arose. The other eight supervisors were presented with an
emergency situation in which standard procedures could not be used. The response
was a management behaviour rating for each supervisor as assessed by a rating scheme
devised by the study’s author. The data are shown on the next page.

and the type of decision making situation? Test at � = .05.

types of training categories? (Test at � = .05).?

types of situations? (Take � = .05).
