What is the Line of Best Fit?

Back

A straight line that best represents the data on a scatter plot, showing the trend of the data.

Front

What does an outlier represent in a data set?

Back

An outlier is a data point that differs significantly from other observations, often indicating variability or an error.

Front

What does it mean if the Line of Best Fit is horizontal?

Back

A horizontal line indicates no correlation between the variables; changes in one variable do not affect the other.

Front

How can you determine if a line is a good Line of Best Fit?

Back

A good Line of Best Fit minimizes the distance between itself and all the data points.
