Graphing

​Situation

There are many science classes offered at a high school. Some are required to take and others are taken by choice.

​

​The amount of students in each class was counted and graphed.

​Easy graph reading and analyzing

Multiple Choice

What information is on the X-Axis?

• High School Science Classes

• Students enrolled

Multiple Choice

What scale is used on the Y-Axis?

• 10 students

• 50 students

• 200 students

​The scale goes up by 50

​The small lines between help you measure in-between amounts. They won't always be there.

​

What value is each small line on this graph?

Multiple Choice

How many students are enrolled in Chemistry?

• 150

• 160

• 175

• 200

Multiple Choice

How many MORE students are enrolled in Chemistry compared to Anatomy?

• 50

• 30

• 100

• 20

​Answer

​Chemistry = 160

​Anatomy = 130

​

​160 - 130 = 30

Multiple Choice

Why is a bar graph used for this data?

• The graph is comparing amount in categories

• The graph is showing changes over time

• The graph is showing how one thing affects another

• The graph is showing parts of a whole

Multiple Choice

A graph title should describe what the graph is about.  Write an accurate title for this graph. 

• Bar Graph

• Amount of Students in Different Science Classes

• Students' Favorite Science Classes
