Question
Identify the important experimental strategy emphasized in the following scenario: A scientist wants to determine whether whitetip reef sharks prefer to eat one species of prey or another. The scientist finds a group, lowers feeding cages with each prey species equidistant from the group of sharks and counts the number of sharks that feed from each cage for 10 minutes. The assistants who are counting the feeding sharks cannot see which species in each feeding cage.
A) randomization
B) replication
C) blocking
D) blinding
E) experimental design
Explanation / Answer
as the group of sharks are feeded with different species and the process is repeated number of times to observe the preference of the shark, as we have seen that the researchers are using different prey therefore the important strategy emphasized here is replication.
we have replicated the process with different species. therefore option B is correct.
