RD Sharma Solutions Class 8 Pictorial Representation Of Data As Pie Charts Or Circle Graphs

RD Sharma Solutions Class 8 Chapter 25

In our day to day life, we come across various information, like:

  1. Goals scored by a player in the last 15 matches.
  2. The number of stumping done by a wicketkeeper in the last 5 T20s.
  3. Marke scored by students in science unit tests.

All these information are known as data. Data is usually collected in the context of a situation that we want to study. For example, The basketball coach of the school basketball team wants to know the average height of students in the school basketball team. For doing this, the football coach will write the heights of all the students playing in the team, organize the data in a systematic manner & then interpret it accordingly.

Sometimes the data is represented graphically to give a clear idea of what it represents:

  1. A Bar Graph: Visualisation of information using bars of uniform width, and the height is being proportional to the respective values.
  2. A Pictograph: A pictorial representation of data using symbols.
  3. Double Bar Graph: It shows two sets of data simultaneously.
  4. Pie Chart: It is a circular statistical graphic which is divided into slices to illustrate numerical proportion.

Our RD Sharma Solutions for class 8 will help students to learn and solve tough mathematics problems easily.
