Question
An agricultural researcher is interested in determining the effect of row spacing on crop yield. He plans to divide a field into four separate subplots and use a different row-spacing in each subplot. He will then repeat this in 9 other fields. At harvest, he will record the yield (in bushels per acre) for each subplot separately to determine the yield for each row spacing plan. Identify the factors in the experiment and the number of levels.

The correct answer is:
**B. row spacing; 4 levels**
In this experiment, the factor is row spacing, and there are 4 different row spacings used across the subplots. The yield is being measured as a response variable, but it is not a factor being manipulated in the experiment.
