Class 6 Maths Chapter 9 Notes Data Handling
→ Data is a collection of numbers gathered to give some information.
→ To get a particular information from the given data quickly, the data can be arranged in a tabular form using tally marks.
The table showing the frequency or count of various items is called a frequency distribution table.
Interpretation can be made from this table.
→ Data that has been organised and presented in frequency distribution tables can also be presented using pictographs and bar graphs.
→ A pictograph represents data in the form of pictures, objects or parts of objects. It can be drawn using symbols to represent a certain number of items or things.
→ The data can be represented by means of a bar diagram or a bar graph. In a bar graph, bars of uniform width are drawn horizontally or vertically with equal spacing between them. The length of each bar represents the respective frequency.
