6.SP.A.3: Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.
What you'll learn
- Explain the role of a measure of center: it summarizes all values in a data set with a single representative number
- Explain the role of a measure of variation: it describes how spread out the values are with a single number
- Distinguish between what a measure of center captures (the typical value) and what a measure of variation captures (the variability around the center), and recognize that both are needed for a complete summary
