Lesson 3
What a Point in a Scatter Plot Means
Problem 1
Here is a table and a scatter plot that compares points per game to free throw attempts for a basketball team during a tournament.
player |
free throw |
points |
---|---|---|
player A | 5.5 | 28.3 |
player B | 2.1 | 18.6 |
player C | 4.1 | 13.7 |
player D | 1.6 | 10.6 |
player E | 3.1 | 10.4 |
player F | 1 | 5 |
player G | 1.2 | 5 |
player H | 0.7 | 4.7 |
player I | 1.5 | 3.7 |
player J | 1.5 | 3.5 |
player K | 1.2 | 3.1 |
player L | 0 | 1 |
player M | 0 | 0.8 |
player N | 0 | 0.6 |
- Circle the point that represents the data for Player E.
- What does the point \((2.1,18.6)\) represent?
- In that same tournament, Player O on another team scored 14.3 points per game with 4.8 free throw attempts per game. Plot a point on the graph that shows this information.
