Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Control Group

A control group is a baseline group in an experiment that does not receive the treatment or intervention being tested. This group is essential for comparison, as it helps researchers determine the effect of the treatment by providing a standard against which the experimental group's outcomes can be measured.

Experimental Group

The experimental group is the group in an experiment that receives the treatment or intervention being tested. In this case, participants in the experimental group received echinacea tea, allowing researchers to assess the effects of this treatment on cold symptoms compared to the control group.

Echinacea

Echinacea is a flowering plant commonly used in herbal medicine, particularly for its purported immune-boosting properties. It is often consumed in various forms, such as tea, to help alleviate symptoms of colds and respiratory infections, making it relevant in studies assessing its effectiveness against such ailments.
