QUESTION:
Consider a sample data set with the following summary statistics: s = 95, \(Q_L=72,\ Q_U=195\).
a. Calculate IQR.
b. Calculate IQR/s.
c. Is the value of IQR/s approximately equal to 1.3? What does this imply?
ANSWER:Step 1 of 3
Here we have the following summary statistics for the sample data.
The sample standard deviation, s = 95.
The lower and upper Quartiles are and respectively.
a)
By definitions, the interquartiles range is given as follows:
= 195 - 72
=
