#### About Class 6 Maths Chapter 9

In 6 Maths Chapter 9 Data Handling, we will study about the ways to record raw data and how to use this data to interpret the result and predict further results. Organization of data using tally marks and frequency distribution then interpret it into pictograph and bar graph.

Pictograph: A pictograph represents data through pictures of objects. It helps answer the questions on the data at a glance.

Bar Graph: Bars of uniform width are drawn horizontally or vertically with equal spacing between them and then the length of each bar represents a particular number. Such method of representing data is called a bar diagram or a bar graph. To represent this we use the process of choosing a scale for the graph. For example, 1 unit on the graph = 100 actual units. We should learn how to read a given bar graph.

Note: To get a particular information from the given data quickly, the data can be arranged in a tabular form using tally marks.
