Exploring Your Class Data to Grow the Best Crops

Part 3C: Get Curious

1. Use Settings A to view your class data (But use Level 1 instead of Level 4). There may be unusual values where some people did not properly follow instructions. Facet the data by Player ID. How many Player IDs exist for your class data?

2. List any Player IDs from your class that you believe should be removed from the dataset.

3. If you decide to remove any Player IDs, provide a brief explanation of your reasoning.

4. Use the App to identify the R-squared value of the regression model using only your data (use your Player ID).

5. Use the App to identify the R-squared value of the regression model for your cleaned class data (use your Group ID and remove any Player IDs that did not follow instructions).

6. Explain why you may expect the R-squared values to be similar, but not exactly the same.

Part 3D:Greenhouse Final Challenge

7. Go back to the main menu and select the Challenge level in the Greenhouse game. Your goal is to play 5 seasons to make the most profit possible based upon any crop, amount of water or nitrate level. Your instructor should provide a Group ID for your class.

Use the following settings for season 1:

• Crop: Corn, Bean Tomato
• Water: 5, 20, 35, 50
• Nitrates: 250, 400, 550
• Test every combination 1 time
• Randomly assign each combination to a plot

After season 1, determine any settings you want for season 2.

Provide a clear description for your settings for season 2:

• Submit a screenshot of one graph using only season 1 data that provides justification for your settings for season 2
• Give a 1-2 sentence explanation for your season 2 choices

Repeat this process for seasons 3, 4, and 5.

After playing five seasons, submit your Player ID and final (season 5) funds to your instructor. Compare your profits with those of your fellow students by entering your Group ID below. Sometimes it can take up to 60 minutes for your class data to show in the app below.

8. Try playing the Farmer Game. It allows you to grow crops and complete numerous other challenges.
