Refer to the example provided. TP-3 Collect your term project data. Make a flowchart of the actual process used during your experiment. It should include enough detail that someone unfamiliar with the process could perform the experiment without your help. Get table of means and standard deviations within individual cells.
Plot means vs. standard deviations and means vs. variances.
Remember, the variance is just the square of the standard deviation. Compute the pooled standard deviation and indicate its degrees of freedom. Turn in part d and the most informative parts of a-c with a short written comment explaining the significance of each. Examine a time series plot of the residuals for trends, patterns or unusual observations. Plot residuals vs. cell means.
