Question
An agricultural researcher is trying to find out the type of fertilizer and the planting density that produces the largest crop in a field experiment.
An agricultural researcher is trying to find out the type of fertilizer and the planting density that produces the largest crop in a field experiment. He assigned different plots of land in a field to a combination offertilizer type (1, 2, or 3) and planting density (1 = low density, 2 = high density, 3= developed), then measured the amount of the crop in pounds (scoop for grain) per acre at the time of harvest. Attached is an TABLE
What to Do! (Using JASP whenever needed):
- What hypotheses need to be tested for the model? What are your findings?
- Is it possible to know how strong the independent variables are on the dependent variable
