3. Bivariate Data
A data that has two variables. (accuracy and speed)

4. Categorical Data
A data that can be grouped by characteristics

5. Cluster
Where most of the data is gathered

6. Outlier
Data that lies “outside” of most of the data; data that is distinctly separate from other data

7. Correlation
Relationship between two variables

8. Positive Correlation
Relationship between two variables in which both variables react in the same way

9. Negative Correlation
Relationship between two variables in which variables react in the opposite ways

10. No Correlation

Two variables do NOT have a relationship with a constant rate of change (slope)

13. Line of Best Fit
A straight line that best represents the data on a scatter plot

14. Trend Line
