The histogram below shows the distribution of times, in minutes, required for 25 rats in an animal behavior experiment to navigate a maze successfully. The histogram has 8 intervals, each with a width of 1 minute and with midpoints at 2, 3, 4, ..., and 9 minutes. The frequencies are 3, 8, 6, 4, 2, 1, 0, and 1.To describe the center and spread of the above distribution, the appropriate numerical measures are:a. the mean and the standard deviationb. the mean and the medianc. the median and the IQRd. the IQR and the standard deviatione. Any of the above would be appropriate, it is just a matter of taste.
