100
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

How to identify outliers for univariate data

What is Q1 - 1.5(IQR) and Q3 + 1.5(IQR)? or 2 SD from the mean?

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

What is the calculator command for generating 3 random numbers from 1 to 9?

randInt(1,9,3)

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 distribution used for finding 10 successes in 15 trials.

What is a Binomial Distribution?

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? or Empirical Rule

300

The proportion of the variation 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

Which 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?

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

The rule for finding the probability of a female given that they are an AP Stats student.

What is P(Female|AP Stats Student) = P(Female AP Stats Student)/P(AP Stats Student)

400
The square of the standard deviation.
What is the variance?
400
Applying a logarithmic transformation to both variables causes this type of model to become linear.
What is a power model?
400

The population is divided into groups. Some groups are randomly selected and all individuals in the chosen groups are sampled.

What is cluster sampling?

400

The rule for finding the probability of obtaining the first success on the 5th trial.

What is P(X=5) = (1-p)^4p

400

The 4 basic principles of experimental design.

What are control, randomize, and replicate, comparison?

500
This calculator command can be used to find the area under a normal distribution and above an interval.
What is normalcdf?
500

The calculator command to find the correlation coefficient between L1 and L2

What is STAT-->CALC-->8:LinReg(a+bx) L1, L2?

500

The effects of two variables on the response cannot be distinguished from each other.

What is confounding?

500

The formula to determine the expected value for a discrete random variable with three possible values.

What is x1(Px1) + x2(Px2) + x3(Px3)?

500

The rule for finding the probability of rolling a fair die three times and getting three fours.

What is P(rolling three 4s) = P(4)*P(4)*P(4) = P(4)3?
