Question: The test matrix and test data below show the results from a full factorial experiment on the effect of 3 variables, roughness (R), pipe diameter (D), and viscosity (V), on pressure drop in a pipe. Perform a Pareto analysis on the data to determine the relative importance of the factors and plot in a Pareto chart.
