the range does not provide any useful information and it is a relatively easy statistic to compute. In order to avoid the problem of dealing with the outliers, however, we can calculate a different measure of dispersion called the interquartile range (IQR). The interquartile range can be found by subtracting the first quartile value (q1) from

The interquartile interval is a method to measure the spread of half 50% of values and is useful as ignoring extreme values. Lower Quartile is (N + 1) / 4 Â ° Value (n is the cumulative frequency, ie 157 in this case) and the upper quartile is the 3 (N + 1) / 4 the value. The difference between these two is the interquartile interval (IQR).
