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 extreme 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

Label, Random Number generate with bounds, Select those unique numbers and survey

What is the process for "describing a sample"

200

The type of distribution that is non-negative and skewed to the right.

What is a chi squared?

200

The number of standard deviations above or below the mean, when performing a significance test?

What is the test statistic?

300

This rule helps to determine what percentage of data falls within 1, 2, and 3 standard deviations from the mean

What is the 68-95-99.7 (or empirical) 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 mutually exclusive events?

300

The condition to use this test includes all expected counts be greater than or equal to 5. 

What is the goodness of fit (or chi-square) test?

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

The "typical" prediction error measured in terms of the units of y. 

What is S= Standard deviation of the residuals?

400

The 4 basic principles of experimental design.

What are comparison, control, randomized, and replication?

400

When the outcome of the first event doesn't impact the probability of the second event

What are independent events?

400

(r-1)(c-1) is the expected counts formula for this test. 

What are chi squared for homogeneity and independence?

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

Refers to the relationship created by minimizing the sum of the squared residuals

What is LSRL?

500

Label, random number generator (with bounds) to  randomly assign to treatment groups, compare results between treatments.

What are the "three steps to setting up an experiment"

500

The formula for combining standard deviations

What is the sqrt of the sum of the variances?

500

The formula for a confidence interval

What is statistic +/- critical value(s.e)?
