Introduction to Terms used in Statistics
Statistics is the formal science of making effective use of numerical data relating to groups of individuals or experiments. It deals with all aspects of this, including not only the collection, analysis and interpretation of such data, but also the planning of the collection of data, in terms of the design of surveys and experiments. Now we will see the examples by used the terms in statistics. (Source: Wikipedia).
Example for Statistics Terms
Example 1
Find out the mean, median,mode,range of the below numbers used by terms in statistics?
2,7,8,10,13,17,19.
Solution
The given numbers are 2,7,8,10,13,17,19.
Mean
This term can find the mean used by the average of the given number. Now get the total value of the given number.
Sum of the given numbers are = 2+7+8+10+13+17+19.
= 76.
Now divided by 7 (Because 7 is the total given numbers) = '76/ 7'
= 10.8.
Median
Median term is the central value of the given number series.
The number series is 2,7,8,10,13,17,19.
The central value of the above series is 10.
So we can say the median value is 10.
Mode
Mode term is a duplicate value of the given series. Here no duplicate value.
So the mode value is null value.
Range
Range term is the subtraction of the least value from the highest value of the series.
Range= 19-2
=17.
Example 2
Solve the mean, median, range of the following series used by terms in statistics?
15,17,21,23,30.
Solution
The given numbers are 15,17,21,23,30.
Mean
Mean is the average of the given number. We solve the total of the given numbers.
Sum of the given numbers are = 15+17+21+23+30
=106.
Now divided by 5 (Because 5 is the total given numbers) = '106/5'
= 21.2.
Median
In mathematical, a central value of the given number series is the median.
The number series is 15,17,21,23,30.
The central value of the above series is 21.
So we can say the median is 21.
Range
Subtract the least value from the highest value of the series.
Range =30-15
=15.
These examples are solved used by terms of statistics.
