... If we divide a cumulative frequency curve into quarters, the value at the lower quarter is referred to as the lower quartile, the value at the middle gives the median and the value at the upper quarter is the upper quartile. A set of numbers may be as follows: 8, 14, 15, 16, 17, 18, 19, 50. The mean ...
