I need to show a scatter diagram using the molecular weight as my x-axis.
Consider the following data on 20 chemical reactions, with Y = chromatographic retention time (seconds) and X = molecular weight (gm/mole). (a) Make a scatter plot. (b) Use Excel to fit the regression, with fitted equation and R2. (c) In your own words, describe the fit.© BrainMass Inc. brainmass.com June 3, 2020, 9:26 pm ad1c9bdddf
A step by step method for regression analysis is discussed here. Regression coefficients, coefficient of determination, scatter diagram and significance of regression model are explained in the solution.
