Question

If mode =18 and median =21, find the value of mean

Answer 1

Hii, Here is your answer.

By the formula,

3 Median = Mode + 2 Mean

3×21= 18+2mean

63=18 + 2mean

2 mean =63-18

2 mean =45

Mean = 45/2

Mean=22.5

Hope it helps.....

Plzz mark me as brainliest.......

Answer 2

Answer:

We can use the Karl Pearson empirical formula for calculating the mean such as mean-mode=3(mean-median).

In this case, we have to drive according to the meridian and able to convey values as 24-18=3x24-3x median range to derive it the median.

Therefore, it is very easy to find the meridian and thus change value with respect to the mode and range of mean calculation.
