What are the features of statistics in plural sense?Explain.

Dear Student,
Features of statistics in plural sense are:

1. It consists of aggregates of facts:
In the plural sense, statistics refers to data, but data to be called statistics must consist of aggregate of certain facts.A single and isolated fact or figure like, 60 Kgs. weight of a student or the death of a particular person on a day does not amount to statistics.

2. It is effected by many causes:
It is not easy to study the effects of one factor only by ignoring the effects of other factors. Here we have to go for the effects of all the factors on the phenomenon separately as well as collectively, because effects of the factors can change with change of place, time or situation.

3. It should be numerically expressed:
A data to be called statistics should be numerically expressed so that counting or measurement of data can be made possible. It means that the data or the fact to constitute statistics must be capable of being expressed in some quantitative form as weights of 60, 70, 100 and 90 Kg. or profits of Rs. 10,000, Rs. 20,000 etc.

4.It should be collected in a systematic manner:
Another characteristic of statistics is that the data should be collected in a systematic manner. The data collected in a haphazard manner will lead to difficulties in the process of analysis, and wrong conclusions.

5.It should be collected for a predetermined purpose:
Before we start the collection of data, we must be clear with the purpose for which we are collecting the data. If we have no information about its purpose, we may not be collecting data according to the needs.

Regards.
