WGU C207 – Data-Driven Decision Making
EXAM COVERAGE
1. Problem-solving and decision-making — define problems, identify objectives, develop
alternatives, evaluate evidence, make decisions, and assess outcomes.
2. Research methods — field research, observations, interviews, surveys, secondary data,
sampling, measurement, and research design.
3. Data collection and data quality — relevant variables, accurate collection, reliability, validity,
bias, completeness, and appropriate data sources.
4. Descriptive statistics — mean, median, mode, range, variance, standard deviation,
distributions, percentiles, and interpretation.
5. Quantitative analysis — numerical comparisons, rates, ratios, trends, relationships, statistical
reasoning, and business interpretation.
6. Statistical tools and inference — samples, populations, confidence concepts, hypothesis
testing, significance, correlation, and interpretation of results.
7. Quality management tools — Pareto charts, control charts, cause-and-effect diagrams,
histograms, check sheets, scatter plots, and process analysis.
8. Data visualization and communication — charts, graphs, dashboards, patterns, trends,
audience needs, and communicating evidence clearly.
9. Decision models and evaluation — alternatives, criteria, expected outcomes, risk, costs,
benefits, sensitivity, and decision effectiveness.
,10. Data-driven organizational improvement — translate findings into action, monitor results,
measure performance, and continuously improve organizational outcomes.
1. A team has collected information involving Pareto chart. Which interpretation or next
step best supports sound decision making? Consider evidence, assumptions,
stakeholder impact, limitations, and the consequences of the selected action when
choosing the best answer.
• Make the decision immediately based on personal preference without examining
evidence, alternatives, or possible consequences.
✓ Apply the concept appropriately because it can rank categories to highlight the
relatively largest contributors to an outcome.
• Ignore contradictory information because only evidence supporting the preferred
conclusion should influence the final decision.
• Change several unrelated factors simultaneously so the organization cannot determine
which action produced the observed result.
Rationale: The correct answer is appropriate because it can rank categories to highlight the
relatively largest contributors to an outcome. Sound decisions require structured reasoning,
relevant evidence, and consideration of limitations and consequences.
2. An organization wants to improve performance using control chart. Which approach
would produce the most useful evidence? Consider evidence, assumptions, stakeholder
impact, limitations, and the consequences of the selected action when choosing the best
,answer.
• Make the decision immediately based on personal preference without examining
evidence, alternatives, or possible consequences.
• Ignore contradictory information because only evidence supporting the preferred
conclusion should influence the final decision.
✓ Apply the concept appropriately because it can monitor process behavior over
time using statistical control limits.
• Change several unrelated factors simultaneously so the organization cannot determine
which action produced the observed result.
Rationale: The correct answer is appropriate because it can monitor process behavior over
time using statistical control limits. Sound decisions require structured reasoning, relevant
evidence, and consideration of limitations and consequences.
3. A team has collected information involving survey. Which interpretation or next step
best supports sound decision making? Consider evidence, assumptions, stakeholder
impact, limitations, and the consequences of the selected action when choosing the best
answer.
• Make the decision immediately based on personal preference without examining
evidence, alternatives, or possible consequences.
• Ignore contradictory information because only evidence supporting the preferred
conclusion should influence the final decision.
, ✓ Apply the concept appropriately because it can collect standardized information
from respondents using structured questions.
• Change several unrelated factors simultaneously so the organization cannot determine
which action produced the observed result.
Rationale: The correct answer is appropriate because it can collect standardized information
from respondents using structured questions. Sound decisions require structured reasoning,
relevant evidence, and consideration of limitations and consequences.
4. A manager must make a business decision using information related to data validity.

measurement represents what it is intended to represent.
