What are statistics
The most common type of average
What is the mean
These two elements combine to form your observed score
What is True Score & Error
Used to make inferences based on a smaller group of data about a larger one
What is Inferential Statistics
The left and right look exactly the same
What is a normal distribution
Used to organize and describe the characteristics of a set of data (the first half of this semester)
What are Descriptive Statistics
Also referred to as "the spread" or "dispersion"
What is Variability
Test A and Test B are used to calculate this
What is parallel forms reliability
In Vegas-style sampling, throw this card away
What is sampling without replacement
How far away from the mean in standard deviations
What is Z scores
This level of measurement is characterized by some underlying continuum
What is Interval Level
Data points that have an undue influence on statistics such as the mean and standard deviation, but not the median
What are Outliers
This test type of validity is important for understanding future behaviors
What is predictive validity
Part of the whole
What is a Sample
Given a sample (mean and standard deviation), what's the luck?
What is a Confidence Interval
This type of chart might be delicious at any time of year
What is a Pie Chart
The average distance from the mean
What is standard deviation
To establish this validity, examine the correlations between the outlandish and the expected
What is construct validity
Talk to one person and then their friends
What is Snowball sampling
Statistical symbol or Super-rare Pokemon
What is "Mu"
Unlike this type of dancing, there are no cowboy hats and boots with this type of chart
What is a Line Chart
The shape of your data when the mean is greater than the median
Reliability coefficients, regardless of type, fall between these two ranges
What is between 0 and 1
Make sure that Georgia is represented as part of the South in the U.S. Census
What is Cluster Sampling
At + and - 3, How sure are we?
