In this paper, we discuss median calculation of interval type grouping and point out some shortcomings in the traditional formula, then revise the criteria to locate median, present a method to estimate median based on mathematical expectation of order statistics in uniform distribution, and finally propose a new median formula.
本文针对组距式资料的中位数计算进行了讨论,指出了传统公式的不足,改进了中位数位置的确定标准,提出了用均匀分布次序统计量的数学期望来估算中位数的方法,并在此基础上推导出新的中位数计算公式。
