A numerical measure of the likelihood that an event will occur
What is probability
100
The event containing all sample points belonging to A or B or both.
What is the Union of A and B
100
A method of assigning probabilities that is appropriate when all the experimental outcomes are equally likely
What is the classical method
100
Probabilities are arranged on this specific scale
What is from 0 to 1
100
A measure of variability computed by taking the positive square root of the variance
What is standard deviation
200
A process that generates well-defined outcomes
What is experiment
200
The probability of an event given that another event already occurred.
What is conditional probability
200
A method of assigning probabilities that is appropriate when data are available to estimate the proportion of the time the experimental outcome has occurred in the past.
What is the relative frequency method
200
If the probability of event A is .75, the probability of the complement of A would be
What is .25
200
A measure of the shape of a data distribution
What is skewness
300
The set of all experimental outcomes
What is the sample space
300
Two events are said to be of this type if they have no influence on each other
What is independent
300
A method of assigning probabilities on the basis of judgement
What is the subjective method
300
Events that have no sample points in common are called this
What is mutually exclusive
300
An unusually small or unusually large data value
What is an outlier
400
A collection of sample points
What is an event
400
A graphical representation for showing symbolically the sample space and operations involving events in which the sample space is a rectangle and events are circles.
What is a Venn Diagram
400
A method of determining possible outcomes when the order does not matter
What is combinations
400
The probability of the sun rising tomorrow is (very, very,very) close to this value
What is 1
400
A theorem that can be used to make statements about the proportion of data values that must be within a specified number of standard deviations of the mean
What is Chebyshev's Theorem
500
The event containing the sample points belonging to both A and B.
What is the Intersection of A and B
500
A graphical representation that helps in visualizing a multiple-step experiment (hint:we did this in class with the coin toss)
What is a tree diagram
500
A method of determining potential outcomes when the order does matter
What is permutation
500
If the probability of event A is .2 and the probability of event B is .9, which event is most likely to occur?
What is Event B
500
A measure of variability, defined to be the largest values minus the smallest value
