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

Multiple Select

Which part of this graph shows no change happening? Select all that apply.

• a

• b

• c

• d

• e

Multiple Select

• a.

• b.

• g.

• d.

• f.

Multiple Choice

What does this graph represent?

• Constant Speed

• Acceleration

• Not moving

Multiple Choice

Which part of this graph shows no change happening?

• A

• B

• C

• D

Multiple Choice

When the slope of a line is negative the function is ...

• Constant

• Decreasing

• Increasing

• Not Negative

Multiple Choice

Which part of this graph shows the graph is decreasing?

• A

• B

• C

• D

Multiple Select

Which parts of this graph shows the graph is increasing? (Select all that apply)

• A

• B

• C

• D

Multiple Select

The intervals the graph is decreasing is at

• When x is between 0 and 2

• When x is between 4 and 5

• When x is between 6 and 10

• When x is between 0 and 6

Multiple Select

The intervals the graph is increasing is at (select all that apply)

• When x is between 0 and 2

• When x is between 4 and 5

• When x is between 5 and 6

• When x is between 0 and 6

Multiple Choice

The intervals the graph is constant at

• When x is between 0 and 2

• When x is between 4 and 5

• When x is between 6 and 10

• When x is between 2 and 4

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.

Michael owns his own window cleaning business. He is cleaning the windows of a three story building. The graph shows his height from the ground floor while washing windows. Choose the correct words to correctly describe each section of the graph.

Section B has a _____ slope and represents going to the _____ floor.

• zero; first

• positive; second

• negative; third

• zero; second

• positive; third
