SIX SIGMA Lean Six Sigma Master Black Belt

What type of knowledge is gained by doing an MSA?

A measurement system has sufficient discrimination if:

When assessing gauge performance, you should look at the following (Choose the best answer).

The following is the best description for the purpose of a process map:

While checking regression model assumptions, an engineer generates the following plot of residuals versus predicted Y. Which of the actions below is the most appropriate next step?

In a regression analysis, model assumptions are validated using which of the following?

For a multiple regression model, the R2 is the parameter that:

When evaluating residuals from a regression model, a Black Belt discovers that she has outliers in the data. What is best course of action for the outliers?

What can you conclude if the Sum of Squares Error is larger than Sum of Squares for the Model?

In analyzing some data, you first try multiple linear regression with all the factors and with interactions (example: Factor A times Factor B is interaction AB) You obtain a multiple regression equation of the form: Response = 15 + .13 A - .30 B - .02 C - .00001 AB + .0000004 AC - .00000013 BC +.000000 ABC. The p-values for most of the factors and interactions are between 0 and .05, except interactions BC and ABC, which have p-values between .4 and .9. Which of the following approaches might be appropriate to simplify the equation?
