Describe the placebo effect during hypothesis testing.

When a medical  intervention produces a positive impact, this is known as the placebo effect. It is caused by a person's expectation that the pill or  potion will be effective, rather than any medication property. This means that patients who are more confident about a good result are more likely to achieve it. Some people  benefit from the administration of an  inactive "look-alike" drug or treatment during this phenomenon. This  substance, also known as a placebo, has no known medical implications..

The placebo effect is believed to be triggered by a person's beliefs, according to one  most common theory. If a person wants a pill to do something, it's likely that the body's own chemistry will produce effects that are close to those of a drug.

Many factors influence how much a placebo affects someone, including:

            The illness that is being treated. 

            The degree to which an individual believes the placebo will benefit.
            The degree to which the answer is subjective. The placebo effect is more likely to work if the patient's perception is subjective (for example, on a pain scale of 1 to 10).
