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
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
Samples in which respondents choose themselves.

What is voluntary response?

200

This is the long run, relative frequency of a chance outcome.

What is probability?

200
The Five Steps to creating and calculating a confidence interval.

What is Parameter, Assumptions, Name the Test, Interval, Conclude?

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
The seven steps to creating and calculating a significance test.

What is Parameter, Hypothesis, Assumptions, Name the test, test statistic, obtain a p value, make a decision?

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

The four characteristics of scatterplots.

What is Direction, outliers, form, and strength?

400
The 3 basic principles of experimental design.
What are control, randomize, and replicate?
400

Two events are ____________ if the occurrence of one event has on effect on the chance that the other event will happen.

What is independent?

400

The correct decision when the significance level is .05 the p value is 0.01.

What is reject the Ho?

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

The use of a regression line for prediction using values of the explanatory variable outside the range of the data.

What is extrapolation?

500

A special kind of blocking, in which each subject receives both treatments or subjects are matched in pairs as closely as possible.

What is matched pairs?

500

P(A and B) = P(A) x P(B)

What is the multiplication rule for independent events?

500

The probability a statistic will take a value as extreme or more extreme, supposing Ho is true.

What is a p-value?
