Question
An interquartile range is
- The difference between the upper and lower quartiles
- The measure of the middle half of the data
- A measure of variability
- All the above
Hint:
The interquartile range (IQR) is the difference between the upper quartile and the lower quartile.
The correct answer is: All the above
Step 1 of 1:
Here, Q3 = third (or, upper) quartile and Q1 = first (or, lower) quartile
IQR = Q3 - Q1
So, the statements are as follows:
- IQR is the difference between upper and lower quartiles
- It defines the middle half (the box part) of the boxplot (i.e., the data)
- It measures the spread of the data around the median, viz., the variability from the median
Final Answer:
The right choice is-- d. All the above
