Question

if coefficient of skewness is 0.32 and standard deviation is 6.5 and mean is 29.6. find mode and median ?

Answer 1

Given J=+.32, ℴ=65, ӯ=29.6,M=?,Z=?

J=ӯ ℴ -z/ ℴ =29.6-Z/6.5=0.32

Or 29.6-Z=0.32x6.5

Or 29.6-Z=2.08

Or -Z=2.08-29.6

Or -Z=27.52

Or Z=27.52

Altranative Formula is :J=3( ӯ-M)/ ℴ

Or 0.32=3(29.6-M)

6.5

Or 0.32x6.5=3(29.6-M)

Or 2.08 =88.8-M

Or 3M=88.8-2.08

Or 3M=86.72

M=28.906
