WGU C207 DATA DRIVEN DECISION MAKING
EXAM QUESTIONS AND ANSWERS 100%
CORRECT!!
, Z-Score - ANSWER Data points only. Measurement of a scores relationship to the
mean. A statistical measure that indicates the number of standard deviations a data
point is from its mean.
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.
