The data from the standards was used to generate a linear regression line using Excel (2000). The equations derived from these lines were used to calculate the concentrations of our lake water samples for each anion. All calculations after integrations were performed using Excel (2000). The results of which are displayed in Table 3. Results

How to Perform a Regression Analysis. We will use Excel to perform a simple linear regression analysis, i.e. we will fit a straight line to the data and then test for a nonzero population correlation coefficient, indicating a linear relation exists. We will need to use the following steps. Make sure the CORRELATIONDATA.xls is still open.

Nov 13, 1989 · Plot these data, and estimate the linear regression of sales on price. Here is an Excel-generated scatter plot. You could unscientifically estimate a regression line with a ruler and a pencil, drawing the line so that it "fits" the pattern of dots. The estimated regression line, from the Excel output, is: Sales (Units) = 644.52 - 42.58(Price in ...
