Fractional Factorial Designs are used to analyze factors to model the output as a function of inputs if Hypothesis Testing in the Analyze Phase was inadequate to sufficiently narrow the factors that significantly impact the output(s).

1. A. True
2. B. False

Correct Answer: A

2. B. Number of runs
3. C. People involved
4. D. Output summary

Correct Answer: B

A Personal Trainer was assessing her workout class participants for their body fat content and had to include data for her analysis. One of the columns listed the range of weight of the people included in the studies. This required plotting a Histogram of the weight of the people assessedfor their body fat content. While drawing the Histogram the x-axis contained a certain scale of data. Pick the scale of data that is appropriate for Histograms.

1. A. Ordinal Scale Data
2. B. Ration Scale Data
3. C. Nominal Scale Data
4. D. Interval Scale Data

Correct Answer: D
