A researcher who is examining the effects of temperature and humidity on the eating behavior of rats uses a factorial experiment comparing three different temperatures (70?,80?,and 90?)and two humidity conditions (low and high).The experiment has ______ level(s)for the temperature factor and a total of ______ treatment conditions.
A)1,3
B)3,6
C)6,6
D)3,2

Question

Quizplus · Accepted Answer

The experiment has 3 levels for the temperature factor and 2 levels for the humidity factor, so the total number of treatment conditions is 3 x 2 = 6. Therefore, the best choice is B: 3 levels for temperature and 2 levels for humidity, resulting in a total of 6 treatment conditions.
