Question

for a data set with upper quartile equal to 55 and median equal to 42 if distribution is symmetric find the value of lower quartile​

Answer 1

Lower Quartile =  29  if for a data set with upper quartile equal to 55 and median equal to 42

Step-by-step explanation:

Median = ( Q₃ + Q₁)/2

Q₁  = Lower Quartile = ?

Q₃ = upper Quartile = 55

Median = 42

=> 42 =  ( Q₃ + Q₁)/2

=> 84 = 55 + Q₁

=> Q₁ = 29

Semi interQuartile range =  ( Q₃ - Q₁)/2  = (55 - 29)/2 = 13
