📖 1 of 2

A line of best fit is a straight line that best represents the data points on a scatter plot. It shows the relationship between two variables, helping to predict future values. To create this line, you can use a method called 'least squares,' which minimizes the distance from each point to the line. For example, if you plot the number of hours studied against test scores, the line of best fit will help you see if there’s a trend - like whether studying more generally leads to higher scores.

📖 2 of 2

If most points cluster around the line, it indicates a strong relationship. The further away points are from the line, the weaker the relationship becomes. This line not only helps visualize data but also allows for making predictions about the outcome based on new input values.
