Interquartile Range Calculator

This simple tool works out the interquartile range of a set of numbers by calculating the 25th and 75th percentiles, and then subtracting the former from the latter (i.e., IQR = Q3 - Q1).

Enter your data into the text box below, and then hit the "Calculate Percentile" button. Note, by default this tool calculates the 50th percentile value (i.e., the median).
