Question

Each year you grow cucumbers during the summer and fall. In the past you have not used any type of fertilizer on your plants. This year you noticed ads for 3 different brands of fertilizers. Megaplant, Greatplant and Happyplant. Each of them claim it will create the biggest plants you've seen. To test their claims, you purchase a bag of each and the directions indicate to use half a teaspoon of fertilizer per plants. Formulate a testable hypothesis. Design an experiment to test your hypothesis. Be specific in your experimental design and include your control. Predict the experimental results that would support your hypothesis

Explanation / Answer

The experiment can be designed in following way:

Prediction: As a prediction, use of fertilizers indeed increase the yeild of the crop but analysis of relative increase in yields of the crop when using different fertilizers demands experimental observations. Thus, only after performing the above mentioned steps, the actual results of the experiments and the efficacy of different fertlizers could be stated.

The above given steps could be followed to test a hypothesis that either of the fertilizers would increase the total yield of the crop in the farm-land as compared to non-fertilized crops.
