Calculating Mean and Median

The assignment calculates the mean and median salary for software trainees at Microsoft. The mean salary is calculated by summing up all salaries and dividing it by the total number of employees, which comes out to be Rs 31,000. For the median, the data is arranged in ascending order and the middle value (5th and 6th position) is found to be Rs 30,000. Since the mean is slightly higher than the median, the best measure of central tendency is considered to be the median.

The career used here for calculating the mean and median is the salary of IT software company
employees for example Microsoft.
Let us have a look over the table giving the required details.
Software trainees Monthly salary in Rs
1 30,000
2 20,000
3 35,000
4 25,000
5 15,000
6 40,000
7 50,000
8 30,000
9 45,000
10 20,000
Now if it is required to calculate the mean salary then it is the sum of total salaries of all
employees divided by total number of software trainees.
Mean = (30,000 + 20,000 + 35,000 + 25,000 + 15,000 + 40,000 + 50,000 + 30,000 + 45,000 +
20,000) / 10
 310000/10
 31000
Hence Mean = 31,000 Rs which is the average salary of an software trainee of Microsoft.
For median arrange the data in ascending order
15000 20000 20000 25000 30000 30000 35000 40000 45000 50000
As the number of data is even hence median is as n/2 and (n+2)/2
10/2 = 5th position and (10+2)/2 = 6th position
So mean at 5th and 6th position
 (30000 + 30000)/2
 30000
Hence median is 30000
As we see that mean is 31000 and median is 30000 hence the best measure of central tendency is
the median as it is lower than mean

This point is almost good to agree as both mean and median are almost same with a difference of
100.
