A bar graph presents the results of a survey using bars.
For example:
A bar graph always has a title that presents the subject of the survey.
The title shows that this bar graph represents the number of spinning tops of each colour at a daycare.
A bar graph has 2 axes: a horizontal axis and a vertical axis. Each axis must have a label to indicate what it represents.
In this graph, the horizontal axis (in red) represents the colour of the spinning tops. The vertical axis (in blue) represents the number of spinning tops.
In a bar graph, the data (results) are illustrated using bars. The number associated with the height of the bar shows the amount of data in each category.
The height of the blue bar reaches the number 2 on the vertical axis. This indicates that there are 2 blue spinning tops.
The height of the yellow bar reaches the number 4 on the vertical axis. This indicates that there are 4 yellow spinning tops.
A bar graph presents the results of a survey using bars.
For example:
A bar graph always has a title that presents the subject of a survey.
The title indicates that this bar graph represents the number of spinning tops in each colour at a daycare.
A bar graph has 2 axes: a horizontal axis and a vertical axis. Each axis must have a label to indicate what it represents.
In this graph, the horizontal axis represents the colour of the spinning tops. The vertical axis represents the number of spinning tops.
The scale on the vertical axis has equal intervals.
The interval between the numbers on the vertical axis is +2.
In a bar graph, the data (results) are represented using bars. The number associated with the height of each bar indicates the amount of data in each category.
The height of the blue bar is aligned with the number 4 on the vertical axis. So, there are 4 blue spinning tops.
The height of the yellow bar is aligned with the number 8 on the vertical axis. So, there are 8 yellow spinning tops.
To interpret a bar graph, analyze each part of the graph while keeping in mind the question asked.

A bar graph presents the results of a survey using bars.
For example:
A bar graph always has a title which introduces the subject of a survey.
The title indicates that this bar graph represents the number of t-shirts of each colour in a 5th grade class.
A bar graph has 2 axes: a horizontal axis and a vertical axis. Each axis has a label that indicates what it represents.
In the following graph, the horizontal axis represents the colour of the t-shirts. The vertical axis represents the number of t-shirts.
The scale on the vertical axis contains equal intervals.
The interval between the numbers on the vertical axis is +2.
In a bar graph, the data (results) are represented using bars. The number associated with the height of the bar indicates the amount of data in each category.
The number associated with the height of the purple bar indicates that there are 4 purple t-shirts. The height of the red bar indicates that there are 8 red t-shirts.
