Bar Graphs

Important Reminders:
- Your bar graph should have a title (ex. Students Favourite Colours).
- The axis should be labeled (ex. colours and number of students).
- Make sure you choose an appropriate scale.
- It would be very difficult to read the data on the sample bar graph (posted above) if the scale had an interval of 50 (the scale increases by 50 each time – 50, 100, 150, 200).
- Bar graph scale should reflect the size of the greatest number in the data
Pictographs
Example: Apples Sold
Here is a pictograph of how many apples were sold at the local shop over 4 months:
Note that each picture of an apple means 10 apples (and the half-apple picture means 5 apples).
So the pictograph is showing:
-
In January 10 apples were sold
-
In February 40 apples were sold
-
In March 25 apples were sold
-
In April 20 apples were sold
