A scatterplot is a type of graph that shows the relationship between two numerical variables by displaying data points on a two-dimensional grid.

Front

What does correlation mean in a scatterplot?

Back

Correlation refers to the relationship between two variables, indicating how one variable may change in relation to another.

Front

What is a positive correlation?

Back

A positive correlation means that as one variable increases, the other variable also increases.

Front

What is a negative correlation?

Back

A negative correlation means that as one variable increases, the other variable decreases.

Back

No correlation means that there is no predictable relationship between the two variables.

How can you tell if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once.

Front

What is the independent variable in a scatterplot?

Back

The independent variable is the variable that is manipulated or changed in an experiment, usually plotted on the x-axis.

Front

What is the dependent variable in a scatterplot?

Back

The dependent variable is the variable that is measured or observed, usually plotted on the y-axis.

Front

What does the x-axis represent in a scatterplot?

Back

The x-axis represents the independent variable.
