The data set below shows prices for concert tickets in 10 major cities. Find the interquartile range (IQR) of the set. How do t
he middle 50% of the prices vary?
1 answer:
Answer: IQR = 16
Step-by-step explanation:
Given the following data:
Cost of concert :
CITY : Q, R, S, T, U, V, W, X, Y, Z
Price : 35,36,42,38, 24,29,25, 44,49, 26
Interquartile range (IQR) = Q3 - Q1
Where,
Q3 = the upper quartile
Q1 = lower quartile
Rearranging the data:
24,25,26,29,35,36,38,42,44,49
Q3 = 42
Q1 = 26
IQR = (42 - 26) = 16
