Dr. Bisell conducts an experiment to see whether hunger makes mice runfaster through a maze. He randomly assigns 25 mice to a control group oran experimental group. Which cannot be a confounding variable?

• Where the experiment takes place

• How hungry the mice are

• The population from which the mice are selected

• The time of day of experiment

A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other is called a

• measure of central tendency

• coefficient

• inferential statistic

• correlation

Define a double blind procedure:

• A statistical procedure that identifies common factors among groups of items

• An experimental procedure in which both the research participants and the research staff are ignorant about whether the research participants have received the treatment or a placebo.

• Any effect on behavior caused by the placebo, which the recipient assumes is an active agent, given to the control group in an experiment.

• A statement of the procedures used to define research variables.
