Data is a collection of information we get from taking measurements.

[Show students a set of objects.] What data could we collect about these objects?

Students may identify color, size, type, use, etc.

[Show students a set of counters or objects in 2 different colors.] What can you say about the colors of these counters?

Answers depend on quantities presented to students. An example: There are 5 red counters and 8 blue counters.

How could you represent the information about the counters?

I could draw a picture of 5 red and 8 blue counters. I could use the numbers 5 and 8. A friend and I could show the two numbers on our hands.

What is a pictograph?

A pictograph is a drawing or type of graph where the number of pictures in each row represents the count of items in a category.

A bar graph is a drawing or type of graph where the height of each bar represents the count of items in a category.

What kinds of attributes can you represent with a pictograph or bar graph?

I can represent categorical attributes like color, or belonging to a particular group, using a pictograph or bar graph.

Why do we use graphs?

Graphs are helpful because they allow us to visualize data in a more concrete way. They also allow us to compare groups more easily, and more concretely, than if we just had numbers.

Why are titles important for graphs?

Titles are important because they let the person reading the graph know what it represents. If a graph is not labeled and does not have a title, it is a drawing without any context and so gives us no useful information.
