Final answer:
The experimental units in the study are the 250 females with severe allergies, and there are two treatments: the new allergy drug and a placebo.
The treatment group receives the drug, while the control group receives the placebo, helping to measure the drug's actual effectiveness against allergy symptoms.
Step-by-step explanation:
An experimental study by a pharmaceutical company investigating the effectiveness of a new allergy drug can be broken down as follows:
Experimental Units and Treatments
- The experimental units are the 250 females aged 30-35 years old who suffer from severe allergies.
- There are two treatments in this experiment: one group receives the new allergy drug and another group receives a placebo.
Explanation of Treatments
The group that receives the actual drug is usually referred to as the treatment group, while the group that receives the placebo is known as the control group. The placebo is designed to look exactly like the drug being tested but does not have an active ingredient. This helps in measuring the true effect of the drug by comparing it against the placebo effect.
Importance of the Study
Such studies are crucial in the medical field as they help determine the efficacy of new treatments. In this case, they also show whether the new allergy drug is more effective than a placebo in reducing allergy symptoms after six months.
