Question

Which technique ensures that personal characteristics of research participants are scattered across different groups, thereby making the groups roughly equivalent at the start of the investigation?

Answer 1

Random assignment is the technique which ensures that personal characteristics of research participants are scattered across different groups, thereby making the groups roughly equivalent at the start of the investigation.

What is Random assignment technique?

• Techniques like flipping a coin, pulling names from a hat, rolling dice, or giving participants random numbers are examples of random assignment.
• For the purpose of randomly assigning individuals to treatment groups in clinical trials, numerous methods have been suggested. Simple randomization, block randomization, stratified randomization, and covariate adaptive randomization are a few of the popular randomization approaches described in this article.
• By assigning participants at random, it is possible to prevent systematic differences between and within groups from existing at the commencement of the experiment.
• As a result, it is safer to attribute any differences between groups that are noted at the end of the trial to the methods or treatments used.
