Graphing Practice

Today students practiced graphing and interpreting data. We started by interpreting a pie chart and line graph. Students then worked independently to create scatter plots on data.

Graphing Practice Problem

Water Temperature in oC	Number of developing clams
15	75
20	90
25	120
30	140
35	75
40	40
45	15
50	0

3. What is the dependent variable?
4. What is the independent variable?
5. What is the optimum temperature for clam development?
