results. The usual way of combining results is to create a graph, and ex-tract information (such as the density) from the slope and y–intercept of the graph. One may be tempted to ask why a graph should be better than merely averaging all of the data points. The answer is that an average is completely unbiased. First calculator finds the line equation in slope-intercept form, that is, . It also outputs slope and intercept parameters and displays line on a graph. We need to find components of the direction vector also known as displacement vector. This vector quantifies the distance and direction of an...Determining the Error of a Standard Curve or Regression Line. How to build Interactive Excel Dashboards.
