Question

What is meant by stastical series ? Describe the different types of stastical series .

Answer 1

When the data is presented in some specific order and sequence it is called as a statistical series. In other words, statistical series is the arrangement of a data in a certain systematic order.

There are three types of series in Statistics and Data: ... For eg: 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 1,2,3,4,5,6,7,8 1,2,3,4,5,6,7,8 is an Individual Series. Discrete Series: Discrete Series is a statistical series in which all the observations are listed out along with their corresponding frequency in the form of a table.

When the data is presented in some specific order and sequence it is called as a statistical series. In other words, statistical series is the arrangement of a data in a certain systematic order.

There are three types of series in Statistical series :

• Individual Series.
• Discrete series.
• Continuous series.

$\huge\mathfrak\green{Individual\; Series}$

Individual Series is a statistical series in which the all the observations are listed out and all the observations have a frequency of 1. For eg: 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 1,2,3,4,5,6,7,8 1,2,3,4,5,6,7,8 is an Individual Series.

$\huge\mathfrak\blue{Discrete\; Series}$

In these series all the items are divided in certain groups, but these groups are not continuous, therefore these series are known as discrete series. The numbered item that fall in every group are shown in each group which are known as frequencies.

$\huge\mathfrak\orange{Continuous\; Series}$

Continuous series means where frequencies are given along with the value of the variable in the form of class intervals. For example. Here: ... are class intervals. (ii) 3, 7, 11, 9, 6 is known as their respective frequencies.
