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 relationship between two quantitative variables.

What is the correlation coefficient (or r)?

200

This command generates ______ from __ to __: randInt(1,9,3)

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

200

The type of variable requires gaps in measurement.

What is a discrete random variable?

200

The formula to calculate the one-sample t statistic.

What is z = (x bar minus mu) divided by (s divided by the square root of n) ?

300

This rule helps to determine if data is normally distributed by checking the proportion of observations within each interval (68-95-99.7).

What is the Empirical Rule?

300

The percent of the variables in the values of y that is explained by the LSRL 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 conditions to use this test include all expected counts be greater than or equal to 5.

What is the chi-square (GOF, homogeneity, or independence) test?

400

The squared 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 10% Condition?

400

The assumptions to be verified for inference about a proportion.

1. Randomness

2. Independence

3. Normal

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

Looking at this helps you decide if a linear model is appropriate to represent the relationship between 2 variables.

What is residual plot?

500

____ allows us to conclude causation because _____.

What is random assignment, it creates groups that are as similar as possible (minimizes confounding variables) so that the treatment is the only difference?

500

What identifies a geometric distribution? 

What is BITS, or until the first success? 

500

p-hat +/- z*SE sub p-hat

What is the confidence interval for a population proportion?
