Question

What is an individual series?

Answer 1

The question which is given is that we have to write the definition of individual series and also explain with examples. For individual series numbers should have a frequency of 1, then this number should be known as individual series. So we will see in detail the solution.

Complete step by step answer:
First of all we will understand the concept of individual series.
Individual series can be defined as statistical series in which all the observations are listed out and all the observations have a frequency of 1.
Now you will understand more clearly with more examples:
Example 1:
1, 2, 3, 4, 5, 6, 7, 8 is an individual series because here you can clearly observe that frequency should be 1.
For any individual series frequency is 1. Because here you can see that number is present only ones therefore frequency is one.
We will take another example of an individual series to make sure that you will identify the individual series.
Example 2:
22, 27, 28, 29, 35, 37, 55, 62 are the 8 numbers listed and none of them have a frequency of more than 1. Thus, by definition the number which is given will be an individual series.

Note:
There is a slight difference between individual series and discrete series, in that individual series, in that individual series have data, with all having frequency as 1, whereas the discrete series also has numbers the frequency is not necessarily equal to 1, it may be more and different from one another.
