This measure of center is more resistant to outliers than the mean.
What is the median?
100
observed y - predicted y
What is the residual?
100
This phrase is used to describe an observed effect so large that it would rarely occur by chance.
What is statistically significant?
100
This type of random variable requires a fixed number of trials.
What is a binomial random variable?
100
The type of significance test used for the mean of a single population when the standard deviation of the population is unknown.
What is a T test (or T procedure)?
200
To calculate, subtract the mean of the distribution from the observed x, then divide by the standard deviation.
What is the z-score (or standardized value)?
200
Measures the direction and strength of a linear relationship between two quantitative variables.
What is correlation (or r)?
200
randInt(1,9,3)
What is the calculator command for generating 3 random numbers from 1 to 9?
200
The type of variable where the probability distribution assigns probability as the area under the density curve above a specific interval.
What is a continuous random variable?
200
The formula to calculate the one-sample z statistic.
What is z = (x bar minus mu sub o) divided by (sigma divided by the square root of n) ?
300
This rule helps to determine if data is normally distributed by checking the number of observations within each interval.
What is the 68-95-99.7 rule?
300
The fraction of the variables in the values of y that is explained by the LSR of y on x.
What is the coefficient of determination (or r squared)?
300
This experimental design involves the random assignment of units to treatments which are carried out separately within each group of units known to be similar in some way that is expected to affect the responses.
What is block design?
300
Events that have no outcomes in common and can never occur simultaneously, for which the addition rule is used.
What are disjoint events (or mutually exclusive events)?
300

OB sampled 200 random students on their opinions about new pizza addition to lunch. The school would like to know if there is a relationship between grade level and pizza opinion. The name of the test required for this?

What is chi square test for independence?

400
The square of the standard deviation.
What is the variance?
400

Whatever the form of the population distribution, the sampling distribution tends to resemble a normal distribution given enough sample sizes. 

What is Central Limit Theorem.

400
The 3 basic principles of experimental design.
What are control, randomize, and replicate?
400
The condition involving the population size that must be satisfied to use sigma divided by the square root of n as the standard deviation of a sampling distribution.
What is 'the population is at least 10 times the sample size'?
400

Researchers need this test to be able to determine if there's convincing evidence that students who went to office hours raises test scores. Given a random sample of test scores before and after going to office hours, what is the test they will perform?

One Sample Matched Pair T Test for Mean Difference.
500

This calculator command can be used to find the 85th percentile of IQ (Mean = 100, SD = 15). 

What is invNorm(0.85, 100, 15) =  115.5

500
Refers to the reversal of the direction of a comparison or an association when data from several groups are combined to form a single group.
What is Simpson's Paradox?
500
The five steps of a simulation.
What are state/describe the problem, state assumptions, assign digits, simulate repetition, and state the conclusion?
500

If I know the prior conditions related to an event, I can update the probability of the event happening using conditional probability. 

For example, if the risk of developing health problems is known to increase with age, I can use this theorem to calculate the risk to an individual of a known age to be assessed more accurately by conditioning it relative to their age, rather than simply assuming that the individual is typical of the population as a whole.

What is Bayes Theorem

500
The formula to estimate the true slope of a regression between the population. 

What is b +/- t*SE
