Which method can be used to find the interquartile range for a set of data? find the difference between the maximum and minimum values. find the difference between the upper and lower quartiles. find the median of the upper half of an ordered data set. find the sum of the maximum and minimum values.

Find the difference between the upper and lower quartiles

Step-by-step explanation:

The INter quartile range is widely used to find out the presence of outliers in any sample

IQR i.e. interquartile range is calcuated as

III quartile-Iquartile

Hence option 2 is right.

Option 1 is wrong because the difference between maximum and minimum values represent the range

Option 3 is wrong since  the median of the upper half of an ordered data set is the third quartile.

Option r is wrong since the sum of the maximum and minimum values

will not give iqr
