Variable
Any condition, event, characteristic, or attribute that can take on different values at different times or with different people
Constant
One value in a given context. It does not change or vary
Frequency Distribution
Displays scores on a variable to reflect how frequently each value is obtained. A classification of data which helps in understanding important features
For most variables, it is bell-shaped, normallycurved, and may be graphically represented
Frequency
The number of times this information appears
Distribution
The way in which something is shared out
Correlation
A mutual relationship or connection between two or more things
Correlation coefficient
A mathematical index that describes the direction and magnitude of a relationship
Magnitude: The closer the value is to (-/+) 1, the stronger the relationship.
Direction: Positive: Variables move in the samedirection
Negative: Variables move in the oppositedirection
