|
|
|
what experimental hypothesis is being tested.
|
|
|
whether the experimental findings will be meaningful.
|
|
|
how the dependent variable is measured.
|
|
|
which experimental treatment, if any, they are receiving.

Detailed explanation-1: -Instead, participants are said to be blind when they do not know if they are receiving treatment or a placebo.
Detailed explanation-2: -In a single-blind experiment, participants do not know which group they have been placed in until after the experiment has finished. Example: Single-blind vaccine study You have developed a new flu vaccine.
Detailed explanation-3: -A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results.
Detailed explanation-4: -Example: Yogurt Tasting The researchers know which yogurt containers are low-fat and which are high-fat, but participants are not told. This is an example of a single-blind study because the researchers know which participants are in the low-and high-fat groups but the participants do not know.
Detailed explanation-5: -To avoid experimenter effects, you can implement masking (blinding) to hide the condition assignment from participants and experimenters. In a double-blind study, researchers won’t be able to bias participants towards acting in expected ways or selectively interpret results to suit their hypotheses.
