The age of the employees of a company are given below.

Find the mean, median and mode.

GIVEN:

FORMULA USED:

Mean =

Median =

Mode = Maximum number of terms

Let ages of employees be x

And number of person be frequency (f)

⇒ For Mean:

Mean =

∑xf = 247 + 315 + 460 + 450 + 432 + 493 + 403

= 2800

∑f = 13 + 15 + 20 + 18 + 16 + 17 + 13

= 112

Mean = = 25

⇒ For Median

Total frequency (N) = ∑f = 112

N/2 = = 56

Which lies in commutative frequency 66

Which is having value of x to be 25

∴ Median = 25

⇒ For Mode

Maximum number of terms(f) in above table is 20

20 terms are of value 23

∴ Mode = 23

CONCLUSION: The data is having Mean to be 25

Mode to be 23

Median to be 25
