The rule that the proportion of times that a particular outcome occurs in many repetitions will approach a single number.
What is the law of large numbers?
100
Consists of n independent trials of the same chance process, each resulting in a success or failure, with probability of success p on each trial.
What is a binomial setting?
100
Describes how the sample proportion varies in all possible samples from the population.
What is a sampling distribution?
100
The equation for the standard deviation of a sampling distribution.
What is √p(1−p)/n?
100
A∩B
What is the intersection of A and B?
200
Knowing that one event has occurred does not change the probability that another event happens.
What is independence?
200
A numerical variable that describes the outcome of a chance process.
What is a random variable?
200
States that when n is large, the sampling distribution of x̄ will be approximately Normal.
What is the central limit theorem (CLT)?
200
The equation for the binomial coefficient.
What is n!/(k!(n−k)!)
200
Binary, independent, Number, and Success (BINS).
What are the conditions for a binomial setting?
300
The long-run relative frequency of a chance outcome.
What is probability?
300
The "average" squared deviation of the values of the variable from their mean.
What is the variance of a random variable?
300
A number that describes a population.
What is a parameter?
300
The equation for the probability that event A happens (sentence form).
What is P(A)=number of outcomes corresponding to event A/total number of outcomes in sample space.
300
A statistic that has a mean of its sampling distribution unequal to the true value of the parameter.
What is a biased estimator?
400
A subset of the possible outcomes in the sample space.
What is an event?
400
Involves adding or subtracting a constant a, multiplying or dividing by a constant b, or both. Can be writtenin the form Y=a+bX
What is a linear transformation?
400
The spread of a statistic's sampling distribution.
What is variability?
400
The equation for the standard deviation of the sampling distribution of x̅.
What is σ/√n?
400
A∪B
What is the union of A and B?
500
The chance that another event will happen given that a certain event has already happened.
What is conditional probability?
500
Consists of repeated trials of the same chance process in which the probability p of success is the same on each trial, and the goal is to count the number of trials it takes to get one success.
What is a geometric setting?
500
A number calculated from a sample that is used to estimate an unknown parameter.
What is a statistic?
500
The equation for the standard deviation of a discrete random variable.
What is σx=√Σ(xi-μx)²pi
500
Graphs that can be used to display the sample space for a chance process.
