Question

The monthly salary of 10 employees in a factory are given below : `5000, `7000, `5000, `7000, `8000, `7000, `7000, `8000, `7000, `5000 find the mean, median and mode

Answer 1

The mean of salaries = Rs 6,600, median = Rs 7,000, mode = Rs 7,000

• Given salaries in ascending order are

        5,000; 5,000; 5,000; 7,000; 7,000; 7,000; 7,000; 7,000; 8,000; 8,000

MEAN:

• Mean = (sum of salaries)/(number of employees)

          $Mean=\frac{5000+5000+5000+7000+7000+7000+7000+7000+8000+8000}{10}$

          $Mean=\frac{66000}{10}$

          $Mean=6,600$

MEDIAN:

• We have even number of observations, hence median is the average of middle two observations

          $Median=\frac{7000+7000}{2}$

          $Median=\frac{14000}{2}$

          $Median=7,000$

MODE:

• Mode is the most repeated observation in given data. 7,000 is the salary with highest frequency i.e, 5.

           $Mode=7,000$
