 As figure 1 shows, the 500 ppm standard ended up making our standard curve nonlinear, so we decided to remove this standard from our data sets for the rest of the trials.
 As figure 2 shows, our final set of standards created a linear standard curve. Our coffee samples were diluted 50% so they would fall between our caffeine standards.
 As figure 3 shows, the decaf coffee had such low concentrations of caffeine that they did not fall between our sets of standards.
