Qualitative graphs

Front

What is a qualitative graph?

Back

A qualitative graph represents relationships between variables without using numerical values, focusing on the shape and direction of the graph.

Front

What does it mean for a graph to be increasing?

Back

An increasing graph shows that as one variable increases, the other variable also increases.

Front

What does it mean for a graph to be decreasing?

Back

A decreasing graph shows that as one variable increases, the other variable decreases.

Front

What is a linear graph?

Back

A linear graph is a straight line that shows a constant rate of change between two variables.

Front

What is a nonlinear graph?

Back

A nonlinear graph is a curve that shows a variable rate of change between two variables.

Front

What does it mean for a graph to be constant?

Back

A constant graph shows no change in the value of one variable as the other variable changes, represented by a horizontal line.

Front

How can you identify an increasing nonlinear graph?

Back

An increasing nonlinear graph curves upwards, indicating that the rate of change is increasing.

Front

How can you identify a decreasing nonlinear graph?

Back

A decreasing nonlinear graph curves downwards, indicating that the rate of change is decreasing.

Front

What does section B represent in a distance-time graph?

Back

Section B may represent a period where the subject is not moving, such as talking to a friend.

Front

How do you determine the time taken to travel a certain distance on a graph?

Back

You can determine the time taken by measuring the horizontal distance on the time axis corresponding to the vertical distance on the distance axis.
