Is this statement true or false?"A contemporaneous control group occurs at the same time as the placebo group."

The statement is true.

Step 1: Understanding the terms A contemporaneous control group in a scientific study or experiment is a group that is observed at the same time as the experimental group. This is done to ensure that the conditions are as similar as possible for both groups, except for the variable being tested.

Step 2: Understanding the context In the context of a placebo group, this would be a group that is given a placebo (a substance with no therapeutic effect) to compare with the group receiving the actual treatment.

Step 3: Making the connection So, if a contemporaneous control group occurs at the same time as the placebo group, it means that both groups are being observed and tested simultaneously. This is a common practice in scientific studies to ensure accurate results.

Therefore, the statement "A contemporaneous control group occurs at the same time as the placebo group" is true.
