Scatterplots

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What does it mean if a scatterplot shows a positive linear association?

Back

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

Front

What does it mean if a scatterplot shows a negative linear association?

Back

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

Front

What is a non-linear association in a scatterplot?

Back

A non-linear association occurs when the relationship between the two variables does not follow a straight line.

Front

How can you predict values using a scatterplot?

Back

You can predict values by finding the corresponding point on the scatterplot that relates the two variables.

Front

What does it indicate if there is no apparent association in a scatterplot?

Back

It indicates that there is no clear relationship between the two variables being plotted.

Front

What is the purpose of using scatterplots in data analysis?

Back

Scatterplots are used to visualize the relationship between two quantitative variables and to identify trends or patterns.

Front

What is the independent variable in a scatterplot?

Back

The independent variable is the variable that is manipulated or changed, typically 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, typically plotted on the y-axis.

Front

How do you identify a linear relationship in a scatterplot?

Back

A linear relationship can be identified if the points in the scatterplot form a pattern that resembles a straight line.
