Statistics - Discrete Series Arithmetic Mode
当数据与其频率一起给出时。以下是离散序列的一个例子 −
When data is given along with their frequencies. Following is an example of discrete series −

在离散序列中，可以通过检查来确定算术众数，并找出与之关联的频次最高的变量。然而，当最大频次与其前一频次或后一频次之间的差异很小时，则使用分组表法。
In discrete series, Arithmetic Mode can be determined by inspection and finding the variable which has the highest frequency associated with it. However, when there is very less difference between the maximum frequency and the frequency preceding it or succeeding it, then grouping table method is used.
