Independent Project: Completion

To complete this independent project, you are to collect the data for your observational experiment and perform a one-way, between-subjects ANOVA on the data using the definitional formula. You are to turn in an APA style paper that includes the following:

1. Description of your research project that includes the operational definitions for your variables and your research question.
2. Description of the 5-steps of hypothesis testing.
3. An APA style statement of results including the appropriate details for the inferential statistic(s) and appropriate descriptive statistics.
4. Interpretation of your results and any limitations you are aware of in your project (everyone should be able to identify at least one potential confounding variable).
5. One graphic representation of your data (table or figure).
6. An ANOVA Summary Table. You will also turn in the step-by-step details of the descriptive and inferential statistics as you calculated them using definitional formulas. This should be included as an appendix to the paper

This is what I was thinking for my experiment could you please help me sort out all the errors and flaws in this project and help design an experiment that supports my original question. 

*** My research project is the independent variable as levels of fertilizer on an agriculture field. Levels are present at 40mg, 60mg, and 80mg.
