Given : Q1 = 62, Q3=86 & coefficient of skewness =0.5
To Find : Median
Solution:
Q1 = 62
Median Q2 = ?
Q3=86
coefficient of skewness =0.5
coefficient skewness = (Q1 + Q3 - 2Q2)/(Q3 - Q1)
=> 0.5 = ( 62 + 86 - 2Q2)/(86 - 62)
=> 0.5 = ( 148 - 2Q2)/(24)
=> 12 = 148 - 2Q2
=> 2Q2 = 136
=> Q2 = 68
Median is 68
if Mean < median -ve coefficient skewness
if Mean > Median + ve coeeficient skewness
