The shape of this distribution.
What is skewed to the right?
This acronym helps us describe a scatterplot completely. (Please name the acronym and tell what they mean).
What is DUFS (Direction, Unusual Features, Form, Strength)?
This statistical concept allows us to generalize our findings to a population.
What is random sampling?
Events that cannot occur at the same time.
What is mutually exclusive? P(A and B) = 0
Actual - Predicted
What is a residual?
The quantity shown in a table where you take how often something happens divided by all outcomes.
What is relative frequency?
These help us make predictions and wear a silly little hat.
What is a regression equation?
This term refers to whatever the subjects are assigned to do in an experiment.
What is a treatment?
This formula can help you find the Probability of A or B occuring...
What is P(A or B) = P(A) + P(B) - P(A and B)?
This statistical concept can help us account for variation in the response due to a certain variable.
What is blocking?
This measure of center is resistant to outliers.
What is the median?
These points weaken or strengthen the correlation in a scatterplot.
What is an outlier?
This statistical concept allows us to establish causation in a well-designed experiment.
What is random assignment?
This probability strategy can help you solve problems with conditional probabilities.
What is a tree diagram (or two way table)?
When the observed results of a study are too unusual to be explained by chance alone.
What is statistical significance?
The percent of values in a distribution between the minimum and Q1.
What is 25%?
This graphic helps us determine the appropriateness of a regression model.
What is a residual plot?
This form of bias refers to when a participant chooses to be a part of the experiment or study.
What is voluntary response?
Knowing whether or not one event has occurred does not change the probability that the other event will happen.
What are independent events?
This sampling method makes sure all groups or categories are represented in a sample.
What is stratified random sampling?
The z-score for the following information:
Value: 10
Mean: 5
SD: 5
What is z = 1?
This statistical measure is unaffected by changes in units.
What is correlation?
The four components of a well-designed experiment.
The number all probabilities for a valid model should add up to.
What is 1?
Mr. Kreider hates this football team.
What is Ohio State?
