NettetWhat is a linear model? If we graph data and notice a trend that is approximately linear, we can model the data with a line of best fit. A line of best fit can be estimated by drawing a line so that the number of points above and below the line is about equal. While a line of best fit is not an exact representation of the actual data, it is a ...
