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 proportion of a single population.

What is a one-sample z test for a population proportion?

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 GENERAL formula to calculate a standardized test statistic.

What is standardized test statistic = (statistic minus parameter) divided by (the standard deviation) ?

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

Finding convincing evidence to reject the null hypothesis when the null hypothesis was actually true.

What is a Type I Error?

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 4 basic principles of experimental design.

What are comparison, random assignment, control, and replication?

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 (2 of the following):

- Randomness

- 10% Condition

- Large Counts Condition?

500

This calculator command can be used to find the area under a normal distribution and above an interval.

What is normalcdf?

500

When describing a scatterplot, one must include descriptions of...

What are direction, unusual features, form and strength?

500

This type of experiment requires that neither the subjects nor those who interact with them and measure the response variable know which treatment a subject is receiving.

What is a double-blind experiment?

500

This term describes two events if knowing whether or not one event has occurred does not change the probability that the other event will happen.

What is independent events?

500

This allows us to estimate a population proportion given some point estimate.

What is the confidence interval for a population proportion?
