Question

Q1. If Mode = 50 and Median 30, find Mean. [.​

Answer 1

Mean = 20

Step-by-step explanation:

3 Median = Mode + 2 Mean

3× 30 = 50 + 2 Mean

90 = 50 + 2 Mean

2 Mean = 90 - 50

Mean = 40/2

Mean = 20

Answer 2

First off, we must know the Empirical Relationship between Measures of Central Tendencies.

You know that Mean, Median and Mode are all Central Tendencies. But all together they have an equation:-

I.e, Mode = 3 Median - 2 Mean

GIVEN: Mode = 50, Median = 30

This means that, 50 = 3(30) - 2[Mean]

--> 50 = 90 - 2Mean

--> 2Mean = 90 - 50

--> Mean = 40/2

=> Mean = 20

∴ If Mode = 50 and Median 30, Mean = 20
