Mean Value Definition
Introduction about mean value definition:
In math,the average of the numbers is known as mean value. It is very simple to calculate. We need to add up all the numbers, and then divide it by how many numbers there are. Let us see the example, find the mean of 2, 7 and 9. Add the numbers: 2 + 7 + 9 = 18.Divide by how many numbers (i.e. we added 3 numbers): 18 3 = 6.therefore, the Mean is 6. Let us see some more examples for the clear understanding.
Example Problems of Mean Value Definition:
Example 1:
Find the value of mean using the given data.
3.4,6, and 12
Solution :
Step 1: First we need to add all the numbers . So, we get 25.
Step 2: From the given data, we have 4 numbers . So, we need to divide using 4.
Step 3: Therefore, '25/4' = 6.25 .The mean value is 6.25.
Example 2:
Find the value of mean using the given data.
6, 9, 34, 23, 14 and 1
Solution :
Step 1: First we need to add all the numbers . So, we get 87.
Step 2: From the given data, we have 6 numbers . So, we need to divide using 4.
Step 3: Therefore, '87/6' = 14.5 .The mean value is 14.5.
Example 3:
Find the value of mean using the given data.
11, 52, 13, 17 , 16, 31, and 4
Solution :
Step 1: First we need to add all the numbers . So, we get 144.
Step 2: From the given data, we have 7 numbers . So, we need to divide using 4.
Step 3: Therefore, '144/7' = 20.5 .The mean value is 20.5.
These are the examples of mean value definition .
Some more Examples of Mean Value Definition :
Example 4:
Find the value of mean using the given data.
12, 9, 14, 44, 5, 8, 10, 13 and 2
Solution:
Step 1: First we need to add all the numbers . So, we get 117.
Step 2: From the given data, we have 9 numbers . So, we need to divide using 4.
Step 3: Therefore, '117/9' = 13 .Therefore mean value is 13.
Example 5:
Find the value of mean using the given data.
15, 5.and 7
Solution:
Step 1: First we need to add all the numbers . So, we get 27.
Step 2: From the given data, we have 3 numbers . So, we need to divide using 4.
Step 3: Therefore, '27/3' = 9 .The mean value is 9.
These are the examples of mean value definition.
