WGU C207 Data Driven Decision Making || Zero Flaw on Answers.
Z-Score correct answers 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 correct answers How far a set of numbers are spread. Used for Data set. Hint Words =
Risk, spread.
Multiplication Rule correct answers 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 correct answers 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 correct answers How many combinations can be made.
Bayes Theorem correct answers 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 correct answers Number halfway into the data set. Hint Word: Typical
Mode correct answers Number that occurs most often in a data set.
Mean correct answers Average. Add all numbers and divide.
, Standard Deviation correct answers How spread out the numbers are. Square root of the
variance.
Pareto Chart correct answers 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 correct answers Shows the causes of a specific event.
Check Sheet correct answers Collect data in real time.
Control Chart correct answers Determines whether a process should undergo a formal exam for
quality.
Histogram correct answers Graph representing the distribution of numeric data. Measures how
continuous data is distributed over various ranges. Example: Displays how many people fall in
various ranges of height.
Scatter Diagram correct answers A graphic that uses dots to show relationships or correlations
between variables
Flow/Run Chart correct answers Shows the workflow process
Bar Chart correct answers Graph of schedule-related info. Example: Measures how many people
are from each state.
Box - Plot correct answers Used while studying the composition of a data set to examine the
distribution (non - parametric data) uses median and percentiles rather than averages. (Look for
Spread and Median.)
Dependent Variable correct answers Dependent upon the Independent variable
