In a normal distribution, this is the rule that describes the percentages that lie within 1, 2, and 3 standard deviations on both sides of the mean.
What is the empirical rule? Also known as the 68-95-99.7 Rule.

For finding the difference in two sample means, one must use this type of procedure...
What is a 2-sample T-interval for difference in means?
300
This is the arranging of experimental units in groups that are similar to one another in order to control lurking variables?
What is blocking?
300
This states that when n is large, the sampling distribution in approximately normal.
What is the Central Limit Theorem?
300
This type of sampling error is due to a lack of people being contacted or included.
What is under-coverage?

This is a randomized block design used when the experiment has only two treatment conditions; and participants can be grouped into pairs, based on some categorical variable.
What is a matched pairs design?
400
This is a graph showing the curve of a cumulative distribution function.
What is an ogive?
400
Unlike a cluster sample, this guarantees that people of a certain type will be included in the survey.
What is a stratified random sample?
400
You roll two dice. The first die shows a ONE and the other die rolls under the table and you cannot see it. This is the probability that both dice show ONE.

500
An extraneous variable in a statistical model that either directly or inversely correlates with the data.
