Question
Name the measure of variability that should be chosen if the median was a good measure of center.
- MAD
- IQR
- Mode
- Median
Hint:
The measure of variability tells us about the spread of data about any measure of central tendency. So, we can primarily opt out of the options median and mode from consideration.
The correct answer is: IQR
Step 1 of 1:
Consider, IQR, i.e., Inter-quartile Range.
The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
Use the IQR when the median is the appropriate measure of center.
Final Answer:
The right choice is-- d. IQR
