The median is the value in the middle of a data set, meaning that 50% of data points have a value smaller or equal to the median and 50% of data points have a value higher or equal to the median. For a small data set, you first count the number of data points (n) and arrange the data points in increasing order. If the number of data points is uneven, you add 1 to the number of points and divide the results by 2 to get the rank of the data point whose value is the median. The rank is the position of the data point after the data set has been arranged in increasing order: the smallest value is rank 1, the second-smallest value is rank 2, etc.
Problem:
A sample of 5 body weights (in pounds) is as follows: 116, 168, 124, 132, 110. The sample median is:
A) 124 *
B) 116
C) 132
D) 130
E) None of the above
