4.7Â Â Â Â Â A group of 15 rats running a straight-alley maze required the following number of trials to perform to a predetermined criterion. The frequency distribution follows.
Trials to reach criterion        18   19   20   21   22   23   24
Number of rats (frequency)Â Â 1Â Â Â Â Â 0Â Â Â Â Â 4Â Â Â Â Â 3Â Â Â Â Â 3Â Â Â Â Â 3Â Â Â Â Â 1
Calculate the mean and median number of trials to criterion for this group. (You can either write out the 15 numbers or you can think about how you could incorporate the frequen- cies directly into the formula for the  mean.)
