Concept explainers
To choose the correct option from the multiple choice question for the question.
Answer to Problem 90E
The option (e) is the correct option.
Explanation of Solution
Statistically designed experiments have three essential features: replication, randomization and control.
Replication means that we need to replicate the experiment with multiple subjects and thus we need to use enough subjects.
Randomization means that we obtain randomization by randomly selecting our subjects or randomly assigning the subjects to treatments groups.
Control means that we require a control group. We then note that answer option (e) best fits the essential features as it refers to replicate and control. Thus option (e) is the correct option i.e. using enough subjects, always having a control group.
