Types of graphs
There are many types of graphs. Learning to read and create graphs is a very useful skill.
Graphs helps us to visualize data. What we see on the graph may help us to interpret and analyze the data.
The end result is usually a better perspective that may not have been possible just by loking at a bunch of numbers.
In this unit, you will learn about pictographs,bar graphs,double bar graphs,line graphs,and circle graphs.
Let us start with pictographs:
is a visual way to display information.
is a graph that uses pictures or symbols to display information.
The pictures in a pictograph usually represent more than one item.
The following is a pictograph:
The graph above has a title and a scale. Let say that the circles were drawn by David, Peter, John, Brown, and Jennifer.
The title is "number of circles drawn"
The scale used is the following: one circle represents 5 circles.
David drew 15 circles since we have 3 circles and each circle represents 5 circles.
John drew 7.5 circles. How did we get 7.5?
Note that if a circle represents 5 circles, half a circle will represent 5/2 circles or 2.5 circles.
Add 5 circles to 2.5, give 7.5
Construct a pictograph with the following table:
Here is the pictographs:
