NCERT Solutions for Class 6 Maths Chapter 9 Data Handling: In a cricket match we can see information like name of the batsman, runs scored, number of balls faced, number of dot balls, number of fours, number of six and strike rate etc. This information will be written in a table for each batsman so that the cricket board can select the best batsman in the match and also this information collected for every match will be helpful to analyze the performance of a batsman throughout his career. Collection of such kind of valuable information is known as data. In NCERT Solutions for Class 6 Maths Chapter 9, we are going to study the collection of numbers gathered together to give valuable information known as data. In NCERT Solutions for Class 6, we will also learn how to represent a data in tabular form using tally marks, using pictogram and also how to draw a bar graph from the collected data and also how to choose a scale for drawing a bar graph.
9.2 Recording Data
9.3 Organisation of Data
9.5 Interpretation of a Pictograph
9.6 Drawing a Pictograph
9.7 A Bar Graph
9.7.1 Interpretation of a bar graph
9.7.2 Drawing a bar graph
From the pictogram and bar graph, we can gather information like the minimum and maximum value of data, in which year minimum occurred, etc. Let's take an example to understand this.
The above bar graph gives information about wheat sold by industry in the year 1998 to 2002. In the bar graph horizontal line represents the year and the vertical line represents wheat sold in thousand tonnes and 1unit = 5000 tonnes. It is clear from the graph wheat sold is maximum in the year 2002 and the amount is 30 units=. Similarly, we can calculate the amount of wheat sold in another year also. Minimum amount is sold in the year 1998. Such many examples are given in the NCERT Solutions for Class 6 Maths Chapter 9 Data Handling
It will be interesting to solve all the questions mentioned in the NCERT Solutions of this chapter.
