A biologist wants to determine if different temperatures (15oC, 25oC, or 35oC) and amounts of sunlight (partial or full) will affect the growth of plants. He will test each combination of temperature and sunlight by randomly assigning 15 plants to each of the combinations.What type of sampling is described in this study?

Answer
A
one sample
B
paired data
C
two samples
D
more than two samples

Explanation

There are 3 temperature levels and 2 sunlight levels, giving 3 × 2 = 6 combinations. The study assigns a separate group of 15 plants to each combination, so it involves more than two samples. The correct choice is “more than two samples.”
