Scatterplots

Front

What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

Front

What does a positive correlation in a scatterplot indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatterplot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does no correlation mean in a scatterplot?

Back

No correlation means there is no apparent relationship between the two variables; changes in one variable do not predict changes in the other.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified by a pattern where points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation can be identified by a pattern where points slope downwards from left to right.

Front

What is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually represent the relationship between two variables and to identify any patterns or correlations.

Front

What is the x-axis in a scatterplot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatterplot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.

Front

What does it mean if a scatterplot has a cluster of points?

Back

A cluster of points indicates that there is a strong relationship between the two variables in that range.
