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 linear association in a scatterplot indicate?

Back

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

Front

What does a negative association in a scatterplot indicate?

Back

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

Front

What does no association mean in a scatterplot?

Back

No association means that there is no discernible relationship between the two variables; changes in one do not affect the other.

Front

What is a nonlinear association?

Back

A nonlinear association occurs when the relationship between two variables cannot be accurately represented by a straight line.

How can you determine the amount of gas left in a tank using a scatterplot?

Back

You can use the scatterplot to find the corresponding value on the y-axis for a given distance on the x-axis.

Front

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

Back

A strong negative correlation means that there is a strong inverse relationship between the two variables; as one increases, the other decreases significantly.

Front

What is the significance of the slope in a scatterplot?

Back

The slope indicates the direction and steepness of the relationship between the two variables.

Front

How do you identify a scatterplot that represents a decreasing value with increasing age?

Back

Look for a scatterplot where the points trend downward from left to right, indicating that as age increases, value decreases.

Front

What is the purpose of analyzing scatterplots?

Back

Analyzing scatterplots helps to identify relationships, trends, and correlations between two variables.
