Statistics - Arithmetic Mode

算术众数是指数据集中出现频率最高的值。换言之,众模值具有与之关联的最高频率。它由符号 ${M_o}$ 或众数表示。

Arithmetic Mode refers to the most frequently occurring value in the data set. In other words, modal value has the highest frequency associated with it. It is denoted by the symbol ${M_o}$ or Mode.

我们将讨论针对三种类型的数列计算正态分佈 Arithmetic Mode 的方法:

We’re going to discuss methods to compute the Arithmetic Mode for three types of series:

Individual Data Series

当数据是以个体为基础给出时。以下是关于个体序列的一个例子:

When data is given on individual basis. Following is an example of individual series:

Items

5

10

20

30

40

50

60

70

Discrete Data Series

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 alongwith their frequencies. Following is an example of discrete series:

Items

5

10

20

30

40

50

60

70

Frequency

2

5

1

3

12

0

5

7

Continuous Data Series

当数据根据范围及其频率给出时。以下是连续序列的一个例子:

When data is given based on ranges alongwith their frequencies. Following is an example of continous series:

Items

0-5

5-10

10-20

20-30

30-40

Frequency

2

5

1

3
