Front

What is a discrete graph?

Back

A discrete graph consists of distinct, separate points. It represents data that can only take specific values, such as the number of students in a class.

What is a continuous graph?

Back

A continuous graph shows data that can take any value within a given range. It is represented by a smooth line or curve, such as the height of a plant over time.

Give an example of a discrete variable.

Back

The number of cars in a parking lot is a discrete variable because it can only take whole number values.

Give an example of a continuous variable.

Back

The temperature in a room is a continuous variable because it can take any value within a range, such as 20.5 degrees Celsius.

Front

What is the main difference between discrete and continuous graphs?

Back

The main difference is that discrete graphs consist of individual points, while continuous graphs represent a range of values with a line or curve.

What is a step function?

Back

A step function is a type of discrete function that jumps from one value to another without taking on any values in between.
