Chapter 2: Presentation of Data

Statistics are measurements or estimates of natural or social phenomenon, usually systematically arranged, analysed and presented.

Details

The data obtained at the end of a sample inquiry or a population inquiry are called raw data or ungrouped data. These are in a haphazard form, so the statistical analysis becomes difficult. Hence it is necessary to arrange data in systematic and short form. A process of arranging ungrouped or raw data into proper form is called classification of data and the data thus obtained are called classified data.
Thus, the method of representing raw data into a systematic and short from is called classification.

In this course we learn the meaning, necessity, and types of classification. Along with this we also learn the types of tables and diagrams and their importance in statistics.
