​QUALITATIVE GRAPHS

Qualitative Graph

​is a graph used to represent situations that may not have numerical values or graphs where numerical values are not included.

​example of a qualitative graph

Notice there are NO numbers on the graph!

Multiple Choice

This is an example of a qualitative graph because

• it is non-linear

• it is linear

• the graphs represents data without number values

• all of the above

When analyzing a qualitative graph, look out for the following item:

Is the line linear or non-linear.

If the graph is linear, it is changing at a constant rate.

Multiple Choice

Which graph below show a graph that is changing at a constant rate?

Also look out for how the graph changes:

Increasing - going up

Decreasing - going down

Constant - no change

When you analyze a qualitative graph, you tell the story of what is happening.

1. In the beginning the water level is at zero.

2. ​The water level increases at a constant rate.

3. The water is turned off and the level does not change.

4. Finally, the drain is pulled, and the water decreases at a constant rate until the tub is empty.

The graph is comparing water levels and time.

Multiple Choice

On a graph comparing speed over time, a section of line with a negative slope means

• that you are going downhill.

• that you are going uphill.

• that your speed is increasing.

• that your speed is decreasing.

Multiple Choice

On a graph comparing distance over time, a section of line with a positive slope means

• the distance is decreasing.

• the distance is staying the same.

• the distance is increasing

• the distance varies.
