The denominator weights each data point based on the error in \(x\) and \(y\) values. The numerator is a measure of the \(y\) distance (or its square) between a data point and our line. Our calculator uses the so-called \(\chi^2\) function as a goodness of fit which is defined as $$\chi^2(m,b) = \sum_,$$ where the sum is over our \(n\) data points. To be able to quantify how good a particular line fits our data, we need to define a function that takes the slope and the intercept of our line and returns a numerical goodness of fit. As we mentioned in the beginning of the page a straight line is represented by the equation $$y = mx b,$$ where \(m\) is the slope and \(b\) is the intercept. Let us first start with the mathematical description of a straight line. \(\chi^2\) per degree of freedom \( \quad = \quad \) To find the best fit of your data, simply copy and paste whole columns or rows directly from Excel into the corresponding boxes below and click the calculate button. If you turn off \(x\) and \(y\) errors below, you will get the same slope and intercept value that you get from Excel’s trendline. It takes the errors in both \(x\) and \(y\) into account and calculates the error in both the slope and the intercept.
