Question

Recall the following salary data from 10 Lad Factory employees.

Staff	1	2	3	4	5	6	7	8	9	10
Salary	20k	21k	22k	20k	19k	20k	18k	21k	100k	105k

Given the mean and median you computed from the data, which measure of central tendency would best serve the purposes of a labor union representative keen on achieving higher salaries for the floor workers? Which would best serve the purposes of the management representatives who are looking to cutting costs? Briefly explain.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
