Question

For a certain frequency distribution mean is 72 and median is 78
find the mode ???..answer..​

Answer 1

Answer:

90 (hopefully it is correct)

Step-by-step explanation:

Using the Empirical formula for Mean, Median and Mode,

3Median = 2Mean + Mode

Here,

Median = 78

Mean = 72

⇒ 3×78 = 2×72 + Mode

⇒ 234 - 144 = Mode

⇒ Mode = 90

∴The mode of the given data is 90
