... Another common measure of center is the median. The median describes the midpoint of a distribution. The median, M, is the midpoint of a distribution, the number such that half the observations are smaller and the other half are larger. The median is the midpoint of a distribution, the number such t ...

... EXERCISE 5 Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet. We randomly sample 49 fly balls. a. If X = average distance in feet for 49 fly balls, then X ____ ( _____ , _____ ) b. What is th ...

... Measures of central dispersion The measures of central tendency (mean, mode & median) do not give a reliable view of the distribution or spread of the data sets and it is possible for two very different data sets to have the same mean, mode and median values. It is often useful to show how far figur ...
