3. What Is Bar Chart? A bar graph is a chart that uses either horizontal or vertical bars to show comparisons among categories. 01

4. shows the specific categories being compared represents a discrete value. Axis Axis 02

5. I t is also possible to draw bar charts so that the bars are horizontal which means that the longer the bar, the larger the category. Horizontal bar chart: 03

6. A grouped or clustered bar graph is used to represent discrete values for more than one item that share the same category. Grouped bar chart: 04

7. What Is Histogram? It is a representation of a frequency distribution by means of rectangles whose widths represent class intervals and whose areas are proportional to the corresponding frequencies. It Looks like 05

8. Simple Example: Consider the following set for example {1,2,2,3,3,3,3,4,4,5,6} we can graph them like this: 06

9. Data Range Frequency 0-10 1 10-20 3 20-30 6 30-40 4 40-50 2 07 Data Ranges :

10. Pie chart: A Pie Chart (or Pie Graph) is a circular chart divided into sectors, each sector shows the relative size of each value. 08

11. Example : Student Grades A B C D 4 12 10 2 09

12. Presented Using a Pie Chart? Pie charts are a visual way of displaying data that might otherwise be given in a small table. Nominal data are categorized according to descriptive or qualitative information such as county of birth or type of pet owned.  Pie charts are generally used to show percentage or proportional data  10
