Line of Best Fit

A line of best fit is a straight line that is drawn through a set of data points on a graph to represent the overall trend or relationship between two variables. It is calculated to minimize the distance between the line and all the points, providing the most accurate summary of how the data behaves. This line helps us predict values and understand patterns, such as whether one variable increases or decreases as the other does. Essentially, it acts as a visual and mathematical summary of the data’s general direction.
