Answers | Get it 100% Correct Answers
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

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.
