Effect of Significant Digits: Example 2: Regression Formatting in Excel

In a series of bringing pragmatic examples of the effect of significant digits, we discuss the influence of using default and scientific formats in the trendline function of Microsoft Excel.  This is the second example (first example was on a beam deflection problem) in the series.

Effect of Significant Digits: Example 1: Beam Deflection

In a series of bringing pragmatic examples of the effect of significant digits, we discuss the exact solution of finding the deflection in a simply supported beam with a uniform load and a tensile axial load.
