RD Sharma Solutions Class 9 Chapter 22

RD Sharma solutions Class 9 Chapter 22 is given here which consists of questions and answers related to statistics.

Statistics represent a sum of total observations. It is always expressed quantitatively not qualitatively. They are always collected with a definite purpose. In an experiment, statistics are comparable and can be classified into various groups.

Statistical data are two types: Primary Data and Secondary Data

After collection of data, the person has to find ways to arrange them in tabular form in order to observe their features and study them. Such an arrangement is called presentation of data. The raw data can be arranged in any of following ways:

(a) Ascending Order, (b) Descending Order (c) Alphabetic Order

When the raw data is put in ascending or descending order of magnitude it is called an array or arrayed data. This data can be studied using different methods of tally marks and frequency distribution. The number of times an observation occurs in the given data is called the frequency of the observation. Frequency Distribution is a method to present raw data in the form which one can easily understand. Frequency Distribution is of two types: Discrete Frequency Distribution and Continuous or Grouped Frequency Distribution.

Understand the concepts of the Cumulative frequency distribution by the solved examples that are easily explained in the RD Sharma solutions.
