Question

Explain the features of statistics.

Answer 1

Hint: Some of the key features of statistics are the aggregation of facts, numerical expressing of information, reasonable accuracy, it is affected by a multiplicity of causes, etc. Describe these features in relation with statistics to get the key features.

Complete step-by-step answer:
Here in this problem, we need to explain the features of statistics.
Statistics is a form of mathematical analysis that uses quantified models, representations, and synopses for a given set of experimental data or real-life studies. Statistics studies methodologies to gather, review, analyze, and draw conclusions from data.
Statistics express information numerically. If a distance between two cities Lucknow and New Delhi is given as $496km$ , then this would be considered as statistical information. The height of a person is measured to be $6.5feet$ , and here the information is recorded using numbers and units, which is statistical information.
In statistics, the data must be collected systematically. The data collected haphazardly will lead to difficulties in the process of analysis, and wrong conclusions. A proper plan should be made and trained investigators should be used to collect data so that they may collect statistics.
Statistics refers to data, but data is called statistics when it consists of an aggregate of certain facts.
Data in statistics must be enumerated or estimated accurately. The statistical statements should be precise and meaningful. If it is infinite or very large, even enumeration of data is impossible and a reasonable standard of accuracy may not be achieved.

Note: Statistics is not just about collecting information, it also deals with organization, interpretation, analysis, and presentation of the data. In applying statistics to a scientific, industrial, or social problem, it is conventional, to begin with, a statistical population or a statistical model to be studied.
