Z-Score
Correct 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
Correct Answer:
How far a set of numbers are spread. Used for Data set. Hint Words =
Risk, spread.
Multiplication Rule
Correct 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
Correct 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
Correct Answer:
How many combinations can be made.
Bayes Theorem
Correct 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
Correct Answer:
Number halfway into the data set. Hint Word: Typical
Mode
Correct Answer:
Number that occurs most often in a data set.
Mean
Correct Answer:
Average. Add all numbers and divide.
Standard Deviation
Correct Answer:
How spread out the numbers are. Square root of the variance.
,Pareto Chart
Correct 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
Correct Answer:
Shows the causes of a specific event.
Check Sheet
Correct Answer:
Collect data in real time.
Control Chart
Correct Answer:
Determines whether a process should undergo a formal exam for
quality.
Histogram
Correct Answer:
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 Answer:
A graphic that uses dots to show relationships or correlations
between variables
Flow/Run Chart
Correct Answer:
, Shows the workflow process
Bar Chart
Correct Answer:
Graph of schedule-related info. Example: Measures how many
people are from each state.
Box – Plot
Correct Answer:
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 Answer:
Dependent upon the Independent variable
Independent Variable
Correct Answer:
Variable the drives the dependent variable
Range
Correct Answer:
Difference between the lowest and highest number in a data set.
Example: 4,6,9,3,7 Range = 9-3 =6
T-Statistic
Correct Answer:
Statistic (derived from a sample) used in hypothesis testing.
Determines if 2 sample means are significantly different from each
other.
Central Limit Theorem
