Blinding is another important aspect of experimental studies. It involves keeping study participants, and sometimes researchers, unaware of which group the participants are assigned to. There are different levels of blinding: - Single-blind: Only the participants are unaware. - Double-blind: Both participants and researchers are unaware. - Triple-blind: Participants, researchers, and those analyzing the data are unaware.
Blinding helps in minimizing bias and ensures that the results are not influenced by participants' or researchers' expectations.
