Question: Using the definitional formula, calculate the (biased) variance of Doty Hall in terms of deviations from the median, rather than the mean, of that distribution

Using the definitional formula, calculate the (biased) “variance” of Doty Hall in terms of deviations from the median, rather than the mean, of that distribution (just put the five scores in numerical order, and use the middle one as the median).

(a) How does this “variance” compare to the σ² that you calculated in Exercise 7?

(b) What property of the variance from the mean is illustrated by this exercise?
