To find mean
Mean = summation of salary x no of employees / Total number of employees
![\operatorname{mean}\text{ = }\frac{14\text{ x 21,000 + 11 x 23,800 + 18 x 26,300 + 4 x 32,000 + 5 x 39,500 + 1 x 145,700}}{14\text{ + 11 + 18 + 4 + 5 + 1}}]()
14 x 21000 = 294, 000
11 x 23,800 = 261,800
18 x 26,300 = 473,400
4 x 32,000 = 128,000
5 x 39,500 = 197,500
1 x 145,700= 145,700
Frequency = 14 + 11 + 18 + 4 + 5 + 1
Frequency = 53

Median = 54/2
Median = 27th position
This implies fall between the 27th position of the employee
The median is $26, 300
