Probability
B.I.N.S.
(Binary, Independent, Number of Trials, Same Probability)
Remember: Fixed number of trials.
What are conditions for a binomial random variable.
Occurs when the null hypothesis is true and is rejected (false positive.)
What is Type I Error?
D.U.F.S.
(Direction, Unusual features, Form, Strength)
What is describing the relationship between two quantitative variables?
A collection of experimental units either not given a treatment of interest or or given a treatment with with an inactive substance (placebo).
What is a control group?
The center of attention in AP Stats.
Who is Jamell Hall?
P(A|B)=P(A and B)/P(B)
What is conditional probability
When the sample size is sufficiently large, a sampling distribution of the mean of a random variable will be approximately normally distributed.
What is the Central Limit Theorem (CLT)?
Used to describe a distribution.
What is S.O.C.S. or S.O.C.V.?
An experiment in which subjects do not know which treatment they are receiving, but members of the research team do, or vice versa.
What is a single-blind experiment?
The mascot of Alonzo and Tracy Mourning Senior High.
What is a shark?
B.I.F.S.
(Binary, Independent, First Success, Same Probability)
Remember: Keep going until a success.
What is a geometric random variable?
Occurs when the alternative hypothesis is true and the null hypothesis is not rejected (false negative.)
What is Type II Error?
The difference between the third and first quartiles: Q3-Q1.
What is interquartile range (IQR)?
Nonresponse, undercoverage, response...
What are Types of Bias?
The #1 shark at ATM aka Papa Shark.
Who is Mr. Shinn?
P(A|B)=P(A)
P(B|A)=P(B)
P(A and B)=P(A) x P(B)
*You only need to check one of these.
What are independent events?
In repeated random sampling with the same sample size, approximately ___ % of confidence intervals created will capture the population parameter.
What is interpret the confidence level?
Gives the strength and direction of the linear relationship between two quantitative variables.
What is correlation (r)?
A variable in an experiment whose levels are manipulated intentionally.
What is explanatory variable?
A sample in which every group of a given size has an equal chance of being chosen.
What is a simple random sample (SRS)?
P(A and B) = 0
What are mutually exclusive (disjoint) events?
We are _____ % confident that the interval from ___ to _____ captures the population parameter (in context.)
What is interpret a confidence interval?
A variable that takes on values that are category names or group labels.
What is a categorical variable?
The systematic tendency to overestimate or underestimate the true population parameter.
What is bias?
A variable related to the explanatory variable and influences the response variable and makes it challenging to determine cause and effect.
What is a confounding variable?
