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 negative relationship in a scatterplot indicate?

Back

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

Front

What does a positive relationship in a scatterplot indicate?

Back

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

Front

What is a linear relationship in a scatterplot?

Back

A linear relationship is when the data points can be approximated by a straight line.

Front

What is a nonlinear relationship in a scatterplot?

Back

A nonlinear relationship is when the data points do not follow a straight line and may curve or cluster in a different pattern.

Front

What does 'no correlation' mean in a scatterplot?

Back

No correlation means there is no discernible relationship between the two variables; the data points are scattered randomly.

Front

How can you identify a linear relationship in a scatterplot?

Back

You can identify a linear relationship by observing if the data points form a pattern that resembles a straight line.

Front

What is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually display the relationship between two variables and to identify trends, patterns, or correlations.

Front

What does it mean if a scatterplot shows a strong correlation?

Back

A strong correlation means that the data points are closely clustered around a line, indicating a strong relationship between the two variables.

Front

What does it mean if a scatterplot shows a weak correlation?

Back

A weak correlation means that the data points are more spread out and do not closely follow a line, indicating a weaker relationship between the two variables.
