HypothesisCorn Yields are affected by the amount of precipitation.
Variable Factors may have an affect on corn yields.
Insufficient precipitation may lead to lower corn yields.

Experiment Process1. Form hypothesis
2. Decide contributing factors3. Plot location of experiment 4. Observe plot and corn crop in
plot5. Research data from previous
years in each field6. Research average precipitation
in Bates Co. for each of those years
7. Make conclusion based on data

Conclusions Derived from DataCorn Yields are affected by the
amount of precipitation.Insufficient precipitation does
lead to lower corn yields.Variable factors do have affect
on corn yields.Additional Conclusion: Excess
precipitation also leads to lower corn yields.
