Making Test Bank Complete Study
Guide and 100% Verified Answers
• 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.
• Histogram . 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.
