the range is the difference between the maximum and minimum values. all the data are within an interval of this width. the interquartile range is the difference between the upper quartile and lower quartile... the interquartile range is therefore a better summary of the spread of marks.

Answer:

It is better to use the interquartile range for the best measure of spread rather than range. If either the maximum or minimum number is an outlier, this can throw off the entire range and misinforms about what the true measure of spread is. The interquartile range is often a more useful piece of information. The difference of the upper quartile and lower quartiles incorporate more actual information and data points from the spread, and are a good representation of the spread of the data.
