Why is it wise to partition experimental resources into a series of smaller experiments rather than conduct a single large experiment?  Can you give an example of why sequential experiments might be wise or prudent?

Reconsider the engine cracking problem experiment described in Problem 12. Suppose that the experimenter only performed the eight trials from replicate I. In addition, she ran four center points and obtained the following response values: 11.53, 12.81, 13.77, 14.41. I’ve included all the relevant data are in the attached file.  Analyze the data and answer the following questions: Midterm12a.dxpx a. Estimate the factor effects. Which effects are large? b. Use the analysis of variance to confirm your conclusions for part (a) and include a check for curvature. Does curvature seem significant? Why or why not? c. Based on this data set, write down a regression model for predicting crack length. Does this differ significantly from the 3 replicate model? That is, are the same factors with similar coefficient values driving the process?
