Scatter Plot Worksheets
Printable data practice for plotting ordered pairs, spotting associations, and using trend lines to make predictions.
Read the Scatter Plot
Each point shows hours of practice and puzzle score. Use the graph to answer the questions.
1. What score matches 4 practice hours?
2. How many points are plotted?
3. Does the score usually go up or down as practice hours increase?
4. Which point has the greatest score?
Plot the Ordered Pairs
Use the table to plot each point on the blank coordinate grid.
| Water cups | Plant height | Point |
|---|---|---|
| 1 | 4 | (1, 4) |
| 2 | 5 | (2, 5) |
| 3 | 7 | (3, 7) |
| 4 | 7 | (4, 7) |
| 5 | 9 | (5, 9) |
| 6 | 10 | (6, 10) |
1. Which ordered pair has the greatest plant height?
2. What point should be plotted for 3 cups of water?
3. Describe the pattern you see.
Match the Association
Decide whether each scatter plot shows a positive association, negative association, or no clear association.
1. Which plot shows a positive association?
2. Which plot shows a negative association?
3. Which plot has no clear association?
Use a Trend Line
Use the trend line to estimate values that are not already in the data table.
| Minutes | Facts correct | Point |
|---|---|---|
| 5 | 12 | (5, 12) |
| 10 | 19 | (10, 19) |
| 15 | 27 | (15, 27) |
| 20 | 34 | (20, 34) |
| 25 | 42 | (25, 42) |
| 30 | 48 | (30, 48) |
1. About how many facts would 18 minutes predict?
2. About how many minutes are needed for 40 facts?
3. Is the trend line a perfect answer or an estimate?
