Research Question: What is the combined effect of fertilizer and watering on cherry tomato plants?

Planters were built that each contained 10 cherry tomato plants. Each planter was identical except that it received a different treatment of water and fertilizer than the other planters. Treatments consisted of a combination of one of four watering schedules and one of three fertilizer concentrations. The plants were tended according to these treatments, and after 65 days, the average number and weight of the tomatoes per plant were measured for each treatment group.

How many different groups are there altogether in this study?

Keenan Michael · Answer 1

Answer: 12

Step-by-step explanation:

Given : Each planter received a different treatment of water and fertilizer than the other planters.

Number of different water schedules = 4

Number of different fertilizer concentrations = 3

By Fundamental counting principle,

Now, the total number of treatment groups in this study = (Number of different water schedules) x (Number of different fertilizer concentrations)

= 4 x 3 = 12

Hence, there are 12 different groups altogether in this study.
