### How do you describe the relationship between two variables?

#### What is the term used to describe an association or interdependence between two sets of data or variables?

How do you describe a relationship in a graph?

The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.

How do you describe relationships in statistics?

A statistical relationship exists if a change in one variable (X) results in a systematic increase in another (Y). The systematic increase doesn’t have to be exact (i.e. up by ten units each time), but it should be approximately the same (“around ten”).

## Is an association among two or more entities?

### When to use correlation in a data set?

#### Which is an example of a positive correlation?

Positive correlation means that as one data set increases, the other data set increases as well. The data in Image 1 has a positive correlation because as years of education increases, so does income. Typically, positively correlated data sets are seen as a line the goes up and to the right on a scatter plot.

How is a Venn diagram used to illustrate a relationship?

Venn diagramsare used to illustrate the relationships between two or more sets. To create a Venn diagram, start by drawing a rectangle to represent the universal set. Next draw and label overlapping circles to represent each of your sets. Most often there will be two or three sets illustrated in a Venn diagram.
