What are the 4 good properties of a experiment'?

Four good properties of an experiment are:

1. Control: Ensures that extraneous variables are minimized, allowing for a clear interpretation of results.
2. Randomization: Helps eliminate bias by randomly assigning subjects to different treatment groups, enhancing the validity of the findings.
3. Replication: Involves repeating the experiment to confirm results, which increases reliability and generalizability.
4. Operational Definitions: Clearly defines variables and procedures, ensuring that the experiment can be understood and repeated by others.
