MOAR SAMPLING
100
Spread is measured by these
What are minimum, maximum, IQR, center, and/or standard deviation?
100
The percentile a person taller than 87% of the population falls into.
What is the 87th percentile?
100
This is a value used to measure correlation and is represented by a value between -1 and 1.
What is r?
100
This appears when a sample is chosen based on its ease.
What is convenience bias?
100
This type of experiment means that neither the experimental groups or the researchers know which is which.
What is a double blind experiment?
200
This method is used to determine outliers in a set of data
What is the 1.5*IQR rule?
200
The area under a normal distribution is always this value.
What is 1?
200
This is the name for r^2.
What is the coefficient of determination?
200
Something that would rarely occur by chance when conducting an experiment is called this.
What is statistically significant?
200
This bias has a great effect on the outcome of answers; diction and structure can create bias.
What is the wording of questions?
300
If the mean of the data is pulled above the median, it is called this.
What is right skewed?
300
The amount of data that falls between one standard deviation above and below the mean of a bell curve is this percentage.
What is 68%?
300
A line is a good fit for a set of data if the graph of the residuals is this shape.
What is a random distribution?
300
This is when two variables are associated in such a way that their effects on a response variable cannot be distinguished from each other.
What is confounding?
300
This variable is not listed as an explanatory or response variable in a study but still affects the explanatory variable.
What is a lurking variable?
400
The five number summary could be used to make this type of graph.
What is a box plot?
400
This is the formula used to determine the Z-score of an observation.
What is Z=(x-μ)/σ *μ=mean and σ=standard deviation
400
This is a description of a scatterplot with an r-value near 1.
What is strong, positive, and linear?
400
This is the set of values between 0 and 9 that is completely random, each having no effect on the next value.
What is a random number table?
400
This is what distinguishes between an experiment and a study.
What is treatment?
500
These are the four characteristics used to describe a distribution.
What are Spread, Outliers, Center, and Shape?
500
This is used to convert a percentile into a Z-score.
What is InvNorm?
500
This is the equation of a least-squares regression line.
What is ŷ = b0 + b1x ?
500
This type of sample gives the same chance of each person being chosen as the next.
What is a simple random sample (SRS)?
500
This method of sampling requires that similar groups be classified based on specific differences before being randomly chosen.
What is stratification?
