What is a non-linear correlation?

Back

A non-linear correlation occurs when the relationship between two variables cannot be accurately represented by a straight line.

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, minimizing the distance between the line and the data points.

How can you determine if a scatter plot has a line of best fit?

Back

You can determine if a scatter plot has a line of best fit by observing if the points cluster around a straight line.

What is the purpose of a line of best fit in predictions?

Back

The line of best fit is used to make predictions about one variable based on the value of another variable.

What does it mean if a scatter plot has no correlation?

Back

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

How can you identify outliers in a scatter plot?

Back

Outliers in a scatter plot are points that fall far away from the general cluster of data points.

Front

What is the significance of the slope of the line of best fit?

Back

The slope of the line of best fit indicates the rate of change between the two variables.
