Question
Find the mean of the following distribution.The daily wages of 50 employees in an organization are given below:Daily wages (in $)100 - 150150 - 200200 - 250250 - 300Number of Workers1213178Find the mean daily wages.
Solution
To find the mean of the distribution, we need to follow these steps:
-
Find the midpoint of each wage range. This is done by adding the lower limit to the upper limit and dividing by 2.
For the wage range 150, the midpoint is $125.
For the wage range 200, the midpoint is $175.
For the wage range 250, the midpoint is $225.
For the wage range 300, the midpoint is $275.
-
Multiply the midpoint of each wage range by the number of workers earning within that range.
For the wage range 150, the total wage is 12 * 1500.
For the wage range 200, the total wage is 13 * 2275.
For the wage range 250, the total wage is 17 * 3825.
For the wage range 300, the total wage is 8 * 2200.
-
Add up all the total wages to get the sum of wages.
Sum of wages = 2275 + 2200 = $9800.
-
Divide the sum of wages by the total number of workers to get the mean wage.
Mean wage = Sum of wages / Total number of workers = 196.
So, the mean daily wage of the 50 employees is $196.
