Amber Adkins is conducting a study on how long it takes a subject to name different types of objects. In her experiment subjects
are asked to name 15 fruits, 15 vegetables and 15 breeds of dogs. Amber has decided to use block randomization for his procedure and has asked for your guidance in setting up the experimental protocol. How many trials should be in each block for Amber’s experiment?
The amount of trials that shouldbe in each block for Amber’s experiment are:
Three
Explanation:
There are two reasons for defining this answer. The first one is that we are taking three general categories to distinguish the three types of elements that form part of the study. Second, these elements will be presented to the individuals and they should at least be offered one option for each group. Therefore the correct question is three. Because we need to include at least an option for each group.
