What is the medium lower quartile upper quartile and interquartil of the numbers

437 456 513 650 893 954 1018 1038 1117 1465

First you find the median, by taking 893+954 and dividing the sum of those two numbers by 2. The median is 923.5. Then you take and find the median of the numbers before the median which is 513. That is your lower quartile. Then you find the median of the numbers below the median, which is 1038. That is your upper quartile. The interquartile range is your upper quartile minus your lower quartile.

Therefore, your answer would be:

Median - 923.5

Lower Quartile - 513

Upper Quartile - 1038

Interquartile Range - 525
