Analyze Phase

On average, there are currently 15 questions in the CSSGB exam from the “Analyze” phase.

Effective August 2022, the number of exam questions from the “Analyze” phase will increase from 15 to 18.

The following are the sections within the “Analyze” pillar of the GB exam, with the cognition level specified for each one.

A. Exploratory data analysis

1. Multi-vari studies

Select appropriate sampling plans to create multi-vari study charts and interpret the results for positional, cyclical, and temporal variation. (Create)

2. Correlation and linear regression

Describe the difference between correlation and causation. Calculate the correlation coefficient and linear regression and interpret the results in terms of statistical significance (p-value). Use regression models for estimation and prediction. (Evaluate)

B. Hypothesis testing

1. Basics

Distinguish between statistical and practical significance. Determine appropriate sample sizes and develop tests for significance level, power, and type I and type II errors. (Apply)

2. Tests for means, variances, and proportions

Conduct hypothesis tests to compare means, variances, and proportions (paired-comparison t-test, F-test, analysis of variance (ANOVA), chi square) and interpret the results. (Analyze)

C. Additional analysis methods

1. Gap analysis

Analyze scenarios to identify performance gaps and compare current and future states using predefined metrics. (Analyze)

2. Root cause analysis

Use cause and effect diagrams, relational matrices, 5 Whys, fault tree analysis, and other problem-solving tools to identify the true cause of a problem. (Analyze)
