This video from SK Knowledge Point discusses different types of diagrams used to represent numerical data, including pictographs, bar graphs, double bar graphs, pie charts, and histograms. It explains that pictographs use symbols to represent data values, while bar graphs and histograms use bars to show frequencies. Pie charts represent parts of a whole through proportional sectors of a circle. Various examples are provided of each type of diagram.

Data handling class 8th
- 1. WELCOME TO MY CHANNEL SK KNOWLEDGE POINT CLASS-8TH(MATHS) CLASS-8TH(MATHS) PRESENTS BY:SANJAY SIR
- 3. Some commonly used diagrams to represent numerical data are: •Pictographs •Bar graph •Double bar graph •Pie-diagrams or Pie-charts
- 4. The information collected in all such cases is called data
- 6. Pictographs represent data through appropriate pictures. In pictographs, the same type of symbol or picture is used to represent the data. Each symbol is used to represent a certain value, and this is mentioned clearly in the graph Pictographs
- 8. A bar graph showing two sets of data simultaneously.
- 9. Grouped data can be presented using histogram. Histogram is a type of bar diagram, where the class intervals are shown on the horizontal axisand the heights of the bars show the frequencyof the class interval. Also, there is no gap betweenthe bars as there is no gap between theclass intervals.
- 10. Histogram
- 11. The data regarding choice of subjects showed the occurrence of each of the entries several times
- 12. Circle Graph or PieChart These are called circle graphs.A circle graph shows the relationship between a whole and its parts. Here, the whole circle is divided into sectors. The size of each sector is proportional to the activity or information it represents
- 13. Its representation in a pie diagram is as shown
