A statistical relationship between variables is referred to as
a correlation
. 1. A correlation between two variables is sometimes called a simple correlation.
How do you analyze the relationship between variables?
When analyzing many variables, scatter plots and
correlation coefficients
can quickly uncover patterns and reduce a large amount of data to a subset of interesting relationships. Correlation describes the strength of relationship between two variables. A correlation coefficient ranges from -1 to +1.
What is the relationship between variables?
The statistical relationship between two variables is referred to as their
correlation
. A correlation could be positive, meaning both variables move in the same direction, or negative, meaning that when one variable's value increases, the other variables' values decrease.

A correlation
is the measurement of the relationship between two variables. These variables already occur in the group or population and are not controlled by the experimenter. A positive correlation is a direct relationship where, as the amount of one variable increases, the amount of a second variable also increases.
What are 3 types of variables?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables:

Why do we need to know the relationship between two variables?
They can tell us about
the direction of the relationship
, the form (shape) of the relationship, and the degree (strength) of the relationship between two variables. The Direction of a Relationship The correlation measure tells us about the direction of the relationship between the two variables.
Is used to examine the relationship between variables?
