Explanation: Statistics is the methodology or methodology that is used for the compilation or collection, presentation and analysis of numerical facts.

characteristics of statistics

1. A set of facts or a conclusion based on it is called statistics. Example- The monthly income of a single person is not a statistic, but the average income derived from the monthly income of many people is called statistical data.

2. The use of statistics does not express the qualitative significance of a fact i.e. good, bad, fair or unfair. On the contrary, every conclusion is expressed by number in the form of percentage, ratio, mean or deviation.

3 In statistics, data is collected keeping in view a pre-determined objective. Statistical data are not scattered here and there, but they are very systematic and planned.

4. Statistics is also related to those data which are comparable with each other. Homogeneous homogeneity in the categories of comparison is essential for comparative study.

5. The presence of sufficient precision in the data is a special requirement of statistics. This means that the nature of the subject of study and the purpose of research should be pure.

limitations of statistics

Statistics can be used only in those studies in which it is possible to explain the facts in the form of numbers.

Statistics can be used only for the study of classes and not in the context of individual values. Statistics cannot be given with reference to individual units nor can much information be obtained.

The conclusions that are obtained on the basis of statistics do not have much credibility.
