WGU C207 DATA DRIVEN DECISION MAKING
ACTUAL EXAM PAPER 2026 QUESTIONS WITH
SOLUTIONS GRADED A+
◉ Variance. Answer: How far a set of numbers are spread. Used for Data
set. Hint Words = Risk, spread.
◉ Multiplication Rule. Answer: A method for finding the probability
that both of two events occur. When the probabilities of multiple events
are multiplied together to determine the likelihood of all of the events
happening. Word Hint: And
◉ Addition Rule. Answer: A method for finding the probability that
either or both of two events occur. When two events, A and B, are
mutually exclusive, the probability that A or B will occur is the sum of
the probability of each event. Word Hint: Either/or.
◉ Combination Rule. Answer: How many combinations can be made.
◉ Bayes Theorem. Answer: Probability of an event , based on
conditions that might be related to the event. Conditional probability. A
formula that calculates conditional probabilities. Important for
, understanding how new information affects the probabilities of
outcomes. Word Hint: Given that.
◉ Median. Answer: Number halfway into the data set. Hint Word:
Typical
◉ Mode. Answer: Number that occurs most often in a data set.
◉ Mean. Answer: Average. Add all numbers and divide.
◉ Standard Deviation. Answer: How spread out the numbers are. Square
root of the variance.
◉ Pareto Chart. Answer: Contains both line and bar graphs. Ordered by
frequency of occurrence that shows how many results were generated by
each identified cause.
◉ Cause and Effect Diagram. Answer: Shows the causes of a specific
event.
◉ Check Sheet. Answer: Collect data in real time.
◉ Control Chart. Answer: Determines whether a process should undergo
a formal exam for quality.
