Find the interquartile range of 437, 456, 513, 650, 893, 954, 1018, 1038, 1117, 1465

The interquartile range is found by subtracting Q1 and Q2. We first need to identify the median to do this we cross out from each side until one or two are left in the middle.

437, 456, 513, 650, 893, 954, 1018, 1038, 1117, 1465

The median is 923.5 found by 893 + 954 / 2 = 923.5

Now we identify the lower median and upper median.

Lower set: 437, 456, 513, 650, 893

Upper set: 954, 1018, 1038, 1117, 1465

Lower set median or Q1: 513

Upper set median or Q3: 1038

We now would find the difference of the two to get the interquartile range.

Interquartile Range: 1038 - 513 = 525
