Answer:
The research study design that includes randomization, control groups, and a treatment intervention is called a Randomized Controlled Trial (RCT).
Step-by-step explanation:
In an RCT, participants are randomly assigned to either a treatment group (receiving the intervention or treatment being studied) or a control group (receiving a placebo or standard treatment). This randomization process helps to eliminate bias and ensures that the groups are comparable at the beginning of the study. By comparing the outcomes between the treatment and control groups, researchers can assess the effectiveness of the intervention and draw conclusions about causality.
Randomized controlled trials are considered one of the most robust and reliable study designs for evaluating the effects of interventions or treatments in medical and scientific research.
