Calculate the average duration of the sample of records presented in a following frequency distribution.   M = . 

Calculate the interquartile range for the data presented in Q13.

In a negatively skewed distribution of exam scores, Mary scored at the mean, Tony scored at the median, and Michael scored at the mode. Who had the lowest score?

Now, assume that an outlier was added to the sample of scores presented in Q27 and this outlier was exactly two standard deviations above the mean. Calculate the raw score of this outlier. X = (round to the nearest whole number).

In a graph below, what dataset has a larger standard deviation?

What does the sigma (σ) denote?
