A set of data’s minimum is 3.0, its
lower quartile is 4.5, its median is 6.4, its upper quartile is 7.9, and its maximum
is 10.1. Determine its interquartile
range.
We know that the interquartile
range of any data set is equal to the upper quarter minus the lower quartile. We are told that the lower quartile
is equal to 4.5. The upper quartile is equal to
7.9. This means that the IQR or
interquartile range is equal to 7.9 minus 4.5. This is equal to 3.4. The interquartile range of the data
is 3.4.
