Question

Calculate the Mean, Median and Mode of the following data:

5, 10, 10, 12, 13.

Are these three equal?

Answer 1

Data is 5, 10, 10, 12, 13

Mean = Sum of all observations/ Number of observations

= (5 +10 + 10 +12 +13)/5

= 50/5

= 10

Since, 10 occurs most frequently i.e., two times.

∴ Mode = 10

Observations are odd in number.

∴ Median = Middle most observation i.e., 3rd observation

∴ Median = 10

Mean = Median = Mode = 10

Yes, these three are equal.
