Question

If the difference of mode and median is 18, then the difference of median and mean is

Answer 1

Answer:

9

Step-by-step explanation:

Mode-Median = 18

then, Mode = 18+median------------(1)

Now, using Empirical formula,

Mode = 3Median-2 Mean

Using (1)

18+Median = 3 Median - 2 Mean

or, Mode - Median = 2 Median - 2 Mean

2( Median- Mean) = 18

Median - Mean = 18/2

or, 9

Hope it helps...... Pls mark me as brainliest

Answer 2

Answer:

Mode =3 median - 2 mean

: Mode = 2 median + median - 2 mean

: Mode - median = 2 median - 2 mean

: Mode -median = 2 (Median - Mean )

Give, difference of mode and median of a data is 18

18 = 2 ( Median - Mean )

18 ÷ 2

Median - Mean = 9

Hope, it will help you
