Chapter 10 Measurement and Inspection
To demonstrate the concept of inherent variability of processes an experiment is available. The task is to click the mouse button on the center of a target. Histograms of the x and y distances between the the center of the target and the cursor location are constructed. The distance is given in terms of number of pixels.
- For each of the three target sizes obtain screen prints of histograms for tests with 15, 30 and 45 trials
- Plot average x distance and average y distance and corresponding standard deviations as functions of number of trials for the three target sizes
