3. A straight line drawn through the center of a set of data points on a scatterplot.
5. Pieces of information obtained through observation.
10. Data that use words to describe how something looks, feels, sounds, or behaves.
14. A circular chart that is divided into sections that show percentages of a whole.
17. A table that shows the number of times a certain outcome or value appears in a set of data.
18. variable: A variable that changes in response to a change in another variable. This is also called a responding variable.
22. Individual observations or pieces of a set of data.
