Category 1
Tells us what values the variable takes and how often
Distribution
How similar or varied observed values are on a graph
Spread
Objects being described in data
for example: people/animals/things
Individuals
Displays percent of each frequency
relative frequency
When specific values of one variable are common with another
association
The measure of asymmetry on a graph
Skewed
Characteristic of an individual, can take on different values
variable
two way table count is the distribution of values of that variable amount all individuals described by the table
marginal distribution
When right and left side of the graph are approximately mirror images
Symmetric
Process of interpreting data
Data analysis
Places an individual into one of several groups or categories
categorical variable
the odds one event will occur given the fact another event already has
conditional distribution
The midpoint of distribution
Median
The pattern or form of data when it’s graphed
Shape
Numerical values for which if makes sense to find an average for
Quantitative variables
Science of learning from data
statistics
A value is this when it falls more or less than 1.5 X IQR + Q3 or - Q1
outliers
Statistical measure that identifies the amount of variation or dispersion of a graph
standard deviation
Displays counts of each category
frequency
the likelihood of two events occurring at the same time
Joint probability
