ASQ SSBB exam contains questions from many topics. These are listed in the Body of Knowledge reproduced below. This version of BOK includes links to Six Sigma Glossary. 

[SIX SIGMA GLOSSARY INDEX OF TOPICS] 
VI. SIX SIGMA IMPROVEMENT METHODOLOGY AND TOOLS  ANALYZE (23 questions) 
A. Exploratory Data Analysis
 Multivari studies
Use multivari studies to interpret the difference between positional, cyclical and temporal variation; design sampling plans to investigate the largest sources of variation; create and interpret multivari charts. (Application)
 Measuring and modeling relationships between variables
a. Simple and multiple least squares linear regression
Calculate the regression equation; apply and interpret hypothesis tests for regression statistics; use the regression model for estimation and prediction, and analyze the uncertainty in the estimate. (Models that have nonlinear parameters will not be tested). (Evaluation)
b. Simple linear correlation
Calculate and interpret the correlation coefficient and its confidence interval; apply and interpret a hypothesis test for the correlation coefficient; understand the difference between correlation and causation. (Serial correlation will not be tested). (Evaluation)
c. Diagnostics
Analyze residuals of the model. (Analysis)
B. Hypothesis Testing
 Fundamental concepts of hypothesis testing
a. Statistical vs. practical significance
Define, compare and contrast statistical and practical significance. (Evaluation)
b. Significance level, power, type I and type II errors
Apply and interpret the significance level, power, type I and type II errors of statistical tests. (Evaluation)
c. Sample size
Understand how to calculate sample size for any given hypothesis test. (Application)
 Point and interval estimation
Define and interpret the efficiency and bias of estimators; compute, interpret and draw conclusions from statistics such as standard error, tolerance intervals and confidence intervals; understand the distinction between confidence intervals and prediction intervals. (Analysis)
 Test for means, variances and proportions
Apply hypothesis tests for means, variances and proportions, and interpret the results. (Evaluation)
 Pairedcomparison tests
Define, determine applicability and apply pairedcomparison parametric hypothesis tests, and interpret the results. (Evaluation)
 Goodnessoffit tests
Define, determine applicability and apply chisquare tests and interpret the results. (Evaluation)
 Analysis of Variance (ANOVA)
Define, determine applicability and apply ANOVAs and interpret the results. (Evaluation)
 Contingency tables
Define, determine applicability, and construct a contingency table and use it to determine statistical significance. (Evaluation)
 Nonparametric Tests
Define, determined applicability and construct various nonparametric tests including Mood's Median, Levene's test, KruskalWallis, Mann Whitney, etc. (Analysis)
