Consider a small unit of a factory where there are 5 employees : a supervisor and four labourers. The labourers draw a salary of Rs 5,000 per month each while the supervisor gets Rs 15,000 per month. Calculate the mean, median and mode of the salaries of this unit of the factory. |

Answer» Salary of supervisor in rupees = 15000 Salary of 4 labourers in rupees = 5000 So, the salaries of all employees in ascending order can be represented as `5000,5000,5000,5000,15000` `Mean = `Sum of all observations`/`Total number of observations `Mean = (5000+5000+5000+5000+15000)/5 = 35000/5 = `Rs `7000` Median can be obtained by finding the middle term. Here, Middle terms are `((n+1)/2)th` term that is third term. So, `Median = `Rs `5000` In the given data frequency of `5000` is maximum as 4 employees has 5000 salary. So, `Mode =` Rs `5000` |
