A Mean
median
Arrange observation in ascending order
4.4 4.6 4.9 5.1 5.1 5.1 5.3 6.0 7.8
Total ovservations are 9 hence middle observation is 5th observation which is 5.1
Hence median is 5.1

In a recent year, according to the Bureau of Labor Statistics, the median number of years that wage and salary workers had been with their current employer (called employee tenure) was 3.5 years. Information on employee tenure has been gathered since the early 1950's using the Current Population Survey (CPS), a monthly survey of 50,000 households that provides information on employment, unemployment, earnings, demographics, and other characteristics of the U. S. population. With respect to employee tenure, the questions measure...

The data below show the wages earned by six workers at three different firms (A, B, and C). The firm's name is shown in column 1 and the workers' wages in column 2. The third column shows the number of times that each firm has been audited for financial fraud while the worker was employed at the firm. The fourth column is a binary variable indicating whether or not the employee works at the accounting department. In the following questions...
