Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot. It shows the general direction of the data points.

What does the equation of the line of best fit represent?

Back

The equation of the line of best fit represents the relationship between the independent variable (x) and the dependent variable (y) in a linear regression.

Front

What does a negative association in a scatter plot indicate?

Back

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

Front

What does it mean if a scatter plot shows no association?

Back

If a scatter plot shows no association, it means there is no discernible relationship between the two variables.

What is a scatter plot?

Back

A scatter plot is a graph that uses dots to represent the values obtained for two different variables, showing their relationship.
