Given Salaries of 29 employees are given below. find the mean salary Salary (in rupees) 20,500 22,500 35,500 16,500 17,000 Employees 7 9 8 2 3

  • Salary (xi)                       Employees (fi)                       fi xi
  • 20,500                                     7                                   1,43,500
  • 22,500                                      9                                  2,02,500
  • 35,500                                      8                                  2,84,000
  • 16,500                                       2                                      33,000
  • 17,000                                       3                                       51,000
  •                                     ∑fi = 29                         ∑fixi = 7,14,000
  • Now Mean = ∑fixi / ∑fi
  •                   = 7,14,000 / 29
  •                   = 24,620.68
