Selina Concise Mathematics Class 7 ICSE Solutions for Chapter 21 - Data Handling

Q: 3. Explain the pie chart and bar graph in data handling.

Pie Chart - Pie chart is also known as a circular chart. It is a kind of chart that represents the data in the circular graph. It divides the circular statistics graphs into sectors or slices to represent the numerical problems. Each sector represents the proportionate part of the whole. Pie charts are widely used to find the composition of something. In most of the situations, pie charts replace other graphs like bar graphs, histograms, line graphs, etc.Bar Graph - Bar graph is the pictorial representation of the group data in the form of horizontal or vertical bars, where the length of the bars is equivalent to the measure of the data, known as bar graph or bar chart.The width of the bars that are drawn on bar graphs are uniform and represented on one of the axes. Also, the measure of the variable is represented on the other axis. The height and width of the bar represent the value of the variable and these graphs are also used to compare the certain quantities. The frequency distribution table can also be formed using the line graph, simplifying the calculations, and helping to understand the data clearly.
