WGU C207 Data Driven Decision Making


Z-Score - answerData 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 - answerHow far a set of numbers are spread. Used for Data set. Hint Words =
Risk, spread.

Multiplication Rule - answerA 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 - answerA 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 - answerHow many combinations can be made.

Bayes Theorem - answerProbability 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 - answerNumber halfway into the data set. Hint Word: Typical

Mode - answerNumber that occurs most often in a data set.

Mean - answerAverage. Add all numbers and divide.

Standard Deviation - answerHow spread out the numbers are. Square root of the
variance.

Pareto Chart - answerContains 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 - answerShows the causes of a specific event.

, Check Sheet - answerCollect data in real time.

Control Chart - answerDetermines whether a process should undergo a formal exam for
quality.

Histogram - answerGraph representing the distribution of numeric data. Measures how

Scatter Diagram - answerA graphic that uses dots to show relationships or correlations
between variables

Flow/Run Chart - answerShows the workflow process

Bar Chart - answerGraph of schedule-related info. Example: Measures how many
people are from each state.

Box - Plot - answerUsed 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 - answerDependent upon the Independent variable

Independent Variable - answerVariable the drives the dependent variable

Range - answerDifference between the lowest and highest number in a data set.
Example: 4,6,9,3,7 Range = 9-3 =6

T-Statistic - answerStatistic (derived from a sample) used in hypothesis testing.
Determines if 2 sample means are significantly different from each other.

Central Limit Theorem - answerDistribution of average of a large number of
independent, identical, variables will be approximately normal. OR the idea that if a
large enough number of samples is taken, the means of those samples will be normally
distributed around the population mean.

F-Statistic - answerValue you get when you run an ANOVA test or a regression analysis
to find out if the means between two populations are significantly different.
