Suppose you are interested in how participants perform under different temperature conditions. You randomly select 30 participants and randomly assign them to work in one of three rooms. The rooms differ only with respect to temperature. You instruct all participants to solve the same jigsaw puzzle, and then you measure how long it takes each one to finish. In this research, the experimenter is investigating whether
a. participants can solve a jigsaw puzzle in different rooms.
b. participants can solve a jigsaw puzzle under different temperature conditions.
c. the time required to solve a jigsaw puzzle depends on temperature.
d. temperature depends on the time required to solve a jigsaw puzzle.
Question 2
Suppose you are interested in how participants perform under different temperature conditions. You randomly select 30 participants and randomly assign them to work in one of three rooms. The rooms differ only with respect to temperature. You instruct all participants to solve the same jigsaw puzzle, and then you measure how long it takes each one to finish. The dependent variable in this research is the
a. jigsaw puzzle. c. temperature.
b. time required to finish the jigsaw puzzle. d. room the participants are in.
