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 counting the successes in 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

The number of standard deviations an observed value falls from a mean.

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

The calculator command used to simulate rolling a standard die 10 times.

What is randInt(1,6,10)

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 -test statistic for a sample proportion.

What is z = (p-hat  -  p0)/sqrt(p0(1-p0)/n)?

300

The area between z = -1 and z = 2 on the standard normal distribution.

What is the 0.815?

300

The fraction 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

This experimental design involves first separating experimental units into groups based on a common characteristic with the goal of reducing variability.

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

The name of the test used to test if the distribution of a categorical variable is the same for 2 or more distinct populations.

What is the chi-square test of homogeneity?

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

The standard deviation of the sample slopes in repeated sampling from a population.

What is the standard error of the slope, or SEb?

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
Two of the conditions to be verified for inference about a proportion.
What are the population size be greater than or equal to 10n and n times p hat & n times (1 - p hat) be greater than or equal to 10? (SRS could also be one of the two)
500

The calculator command that returns the 90th percentile on the standard normal distribution.

What is invNorm(0.9)

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 final step when describing the design of an experiment which has multiple treatment groups?

What is "compare the response variable for the different treatment groups?

500
