From me: (2
points)
Identify the IV(s), DV(s), and the scale of measurement for
each IV and DV.
- Subjects
participated in an experiment designed by Professor Roger Stanton to test the effects of frustration
on aggression in St. Mary's College of Maryland students. The group first
received a frustrating puzzle to solve and the level of aggression
displayed by the St. Mary's College of Maryland students was measured on a scale of 1 - 7. Two days later, Professor Stanton gave a
less-frustrating version of the same puzzle (it was easier) and again the
level of aggression was measured.
Presentation of the two puzzles was counterbalanced across the
participants. Professor Stanton also
investigated the effects of gender (men and women) under the two puzzle
conditions.
- Professor Roger Stanton believes that alcohol intoxication at half the legal limit,
that is, .05 blood alcohol level (BAL) instead of .10 might severely
impair driving ability. To test
this, volunteers from St. Mary's College of Maryland were randomly assigned to the following groups: 10 were given a driving simulation test
while sober (BAL = 0.0), another 10 were tested after drinking and
obtaining a .05 BAL, and a third set of 10 were tested after reaching a
.10 BAL. Professor Stanton measured
performance as the number of simulated obstacles with which the driver
collides.
