    Hi Paul. My tutor has only given me one batch of measurements with a total frequency of 100. He wants me to perform an SPC analysis on the first task and perform a Process Capability study. It really confuses me because I only have one set of data and I've seen alot of people draw distribution curves for SPC analysis. Does that mean that I have to draw two sets of Cp/Cpk graphs. Also... with only one batch of information how do I know where to move the distribution curve over too in order to calculate Cpk?

      Fair play to your lecturer, he's making you do it thoroughly. In that case, job one is to plot the 100 points on a run chart. As part of that exercise. Work out the moving range. In other words take away data point 2 from data point 1 and then 3 from 2, 4 from 3 etc and plot that data on a run chart..
