EXERCISE 1: DATA INTERPRETATION 1. What patterns do you observe based on the information in Table 4? 2. What type of graph is most appropriate to present the data in Table 4? Create a graph of the data in Excel or another graphing software and submit it to your instructor. You can upload the graph as a separate document if that is helpful. If you want to make a graph by hand on graph paper and upload a scan or picture of that graph, I will also accept that. I am more concerned that you understand how to make a graph than how to use Excel. 3. Is it easier to observe patterns and see the connection between lead concentration in soil and the number of plants using a graph or table? After creating your graph, would you change your answer to Question 1? 4. Develop a detailed hypothesis for your experiment. 5. What would your experimental approach be to test this hypothesis? Be detailed in your description of the experiment. 6. What are the independent, dependent, and controlled variables in your experiment? 7. What type of graph would be appropriate for this data set? Why? Table 4. Plant Growth and Soil Lead Concentration Lead Concentration (mg lead/kg soil) 0 20 20 Number of Plants Observed 48 45 40 40 40 40 60 60 80 100 120 140 160 180 34 34 23 13 7 2 1 0
