Simply put, it is

If the number of numbers is odd, then the number corresponding to the number+1/2 is the median EG:2 5 6 8 7 4 9, and the median is: 7+ 1/2=4, which is the fourth from the left.

If the number of numbers is even, then the quotient of this number+the number corresponding to this number /2+65438+ 0 /2 of the sum of the numbers corresponding to this number is the median of this set of data, eg: 254698. The median is: 6/2=3 6/2+ 1=4, which is (4+6)/2.

Mode:

Generally speaking, the number with the highest frequency in a set of data is called the mode of this set of data.

For example, the mode of 1, 2,3,3,4 is 3.

However, if two or more numbers appear the most frequently, then these numbers are all data patterns of the group.

For example, the modes of 1, 2, 2, 3, 3 and 4 are 2 and 3.

Similarly, if all data appear the same number of times, then this set of data has no pattern.

For example: 1, 2, 3, 4, 5 has no pattern.

Question 2: What do median and mode mean? The median is the number in the middle of many elements in * * *

For example, if a * * * is {1, 2, 5, 6, 8, 55, 80} and a * * * has seven numbers, then the median is "6" and ranks fourth.

A pattern is a number that can represent most situations.

For example, the salary subscription of a company is as follows: 1 employee 10000 yuan, 2 employees 5000 yuan, 5 employees 3000 yuan, and 20 employees 1000 yuan.

So here, what can represent the income of most people is the mode, which is 1000.

Question 3: What do median and mode mean respectively? Median: arrange a set of data in order of size, and call a number in the middle position (or the average of two numbers in the middle position) as the median of this set of data. The size of the median is only related to the arrangement position of the data. So the median is not affected by the size of the number. When the individual data in a group of data changes greatly, it is often used to describe the centralized trend of this group of data.

Pattern: The data with the highest frequency in a group of data is called the pattern of the group of data. Therefore, looking for a set of data patterns does not need to be calculated or sorted, but only needs to count the frequency of data with more occurrences. There is a close relationship between mode and probability. The size of a pattern is only related to some data in a set of data. When a set of data is repeated many times, its pattern is often the concentrated trend we care about.

Median: refers to the average level of data, but not all.

Mode: indicates the general situation of data, but it is not as accurate as the average.

Question 4: What is the mode in the mathematical concept? The median mode refers to the number that appears most frequently in a set of data. Median refers to the middle number after a set of data is arranged in order (that is, from large to small or from small to large). If there are even numbers in this set of data, the median is the average of the middle two numbers.

Question 5: What do mean by average, median and mode? What is the difference? 1. average: a set of data. Divide the sum of this set of data by the total score, and the number is the average of this set of data. The size of the average is related to each data in a set of data, and the change of any data will cause the change of the average, that is, the average is affected by a larger number and a smaller number. 2. Median: arrange a group of data in order of size, and call a number in the middle position (or the average of two numbers in the middle position) as the median of this group of data. The size of the median is only related to the arrangement position of the data. So the median is not affected by the size of the number. When the individual data in a group of data changes greatly, it is often used to describe the centralized trend of this group of data. 3. Mode: The data with the highest frequency in a group of data is called the mode of this group of data. Therefore, looking for a set of data patterns does not need to be calculated or sorted, but only needs to count the frequency of data with more occurrences. There is a close relationship between mode and probability. The size of a pattern is only related to some data in a set of data. When a set of data is repeated many times, its pattern is often the concentrated trend we care about. Average value: represents the overall level of data, but cannot represent the differences between individuals. Median: represents the middle level of the data but not the overall pattern: represents the general situation of the data but is not as accurate as the average.

Question 6: Meaning of mode, median and mode: refers to the value that appears most frequently in a set of data. The pattern may be greater than 1.

Median: refers to the number in the middle of a group of data arranged from small to large. It can be the data of an arc is odd) or the average of two (the data is even).

There is no intermediate value. You mean average, right?

Average value: the sum of a set of data divided by the number of this set of data is the average value.
