Line of best Fit

Front

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, showing the trend of the data points.

Front

How do you determine if a line is an accurate line of best fit?

Back

A line is an accurate line of best fit if it minimizes the distance between itself and all the data points, ideally passing through the center of the data distribution.

Front

What does a positive association in a graph indicate?

Back

A positive association indicates that as one variable increases, the other variable also increases.

Front

What does a negative association in a graph indicate?

Back

A negative association indicates that as one variable increases, the other variable decreases.

Front

What does 'no correlation' mean in a scatter plot?

Back

'No correlation' means there is no discernible relationship between the two variables; changes in one do not predict changes in the other.

Front

What does it mean if the slope of a line of best fit is negative?

Back

A negative slope indicates that there is a negative association between the variables; as one variable increases, the other decreases.

Front

How can you visually assess the accuracy of a line of best fit?

Back

You can visually assess the accuracy by observing how closely the line follows the trend of the data points and how well it minimizes the distance from the points.
