What is the percent of other points in a sample that are equal to or less than a given value
This type of bias occurs when some members of a population are left out or are less likely to be included in a sample
What is undercoverage?
This equation will prove that variable A and variable B are independent.
What is P(A ∩ B) = P(A) * P(B)?
Also acceptable:

What is a high leverage point?
This experiment-killer has a correlation with the independent variable and potential causation with the dependent variable
What is a confounding variable?
This is the name for the probability of an event not happening
What is the complement?
How much did California citizens' spending on environmental conservation change after Leonardo DiCaprio publicly announced his support for the environment? You observe the spending habits of 1500 people before and after Leonardo DiCaprio launched his environmental campaign. The correct inference procedure would be a...

For the LSRL relating x= the amount of soap (oz) and y= the number of bubbles, the r^2 value is .922. The interpretation of this r^2 is...
What is about 92.2% of the variability in the number of bubbles is accounted for by the LSRL relating x= the amount of soap (oz) and y=the number of bubbles.
You want to know how many people think AP Statistics is the best class, but you're worried that the answers may differ by grade, so you randomly select 10 students from each of the four grades. This type of sample is known as...
What is a stratified random sample?
This law states that if we do something many, many times, the proportion of desired outcomes will approach its probability
What is the Law of Large Numbers?
p̂c is used for this type of inference procedure
What is a hypothesis test for the difference between proportions?

This type of linearization model transforms (x, y) into (lnx, lny)
What is the power model?
A well-designed experiment has a control group, uses random assignment, controls confounding variables, and has this
What is replication?
These are the conditions for determining that you have a binomial situation
What is:
B - binary (cearly defined success and failure)
I - independence
N - number (defined # of trials)
S - same probability of success each time.
These are the conditions that must be met to perform inference for slope
