Add Best Fit Line Excel is a statistical tool used in Microsoft Excel to calculate and display the line of best fit for a set of data points. It allows users to quickly and easily identify trends and patterns in their data, making it a valuable tool for data analysis and forecasting.
The line of best fit is a straight line that most closely represents the relationship between two variables in a data set. By adding a best fit line to a scatter plot, users can determine the direction and strength of the correlation between the variables. This information can then be used to make predictions about future values or to understand the relationship between different factors.
