Will the intequartile range always be less than the range for a set of score? Is there an example of a time that the intequartile range will be greater?
The interquartile range will always be less than or equal to the range.
By definition of the range, which is the highest minus the lowest, it is not possible that the interquartile range be greater than the range.
For an example where interquartile range equals the range, see:
