What type of experiment is it when only the subject does not know if they are receiving the real treatment or the placebo?
This type of experiment is known as a single-blind study. In a single-blind study, the participants are unaware of whether they are receiving the actual treatment or a placebo, which helps to minimize bias in their responses. However, the researchers conducting the study know which participants are receiving the treatment and which are receiving the placebo. This design helps to ensure that any observed effects can be attributed to the treatment itself rather than participants' expectations.

What type of experiment is it when only the subject does not know it they are receiving the real treatment of the placebo?
If the experimenters know but the subject does not, it's called a "single blind" study. If the placebo is randomized and neither the subject nor the experimenters know which is the placebo, it's called a "double blind" study.
What is a placebo variable?
A placebo is a treatment, most commonly a medication of some kind, which is given to a subject with the pretense that it will treat a specific ailment when in fact the treatment will have no significant effect on the subject. The subject may report that the treatment has had a positive effect, when in fact the effect is entirely in the imagination of the subject. Therefore, a placebo variable is a factor that researchers in the medical field must consider when experimenting with new treatments, to decide whether the success of the treatment is due to the psychological or placebo effect of the treatment, or if the treatment itself is working.

It is the thing you conduct your experiment on.
Factor in a scientific experiment that is subject to change?
A factor in a scientific experiment that is subject to change is called a variable.

In an experiment a group that receives no treatment is called what?
The group that receives no treatment in an experiment is called the control group. This group is used as a point of comparison to evaluate the effects of the treatment applied to the experimental group.

What is a double blind drug?
A double-blind study means that neither the test subject (human) or the researcher administering the study knows whether the test subject is receiving the experimental treatment or the control treatment. Often in human drug tests, the control treatment will be a placebo. This ensures that neither party can make any expectations as to whether they should or shouldn't be seeing results. This is important because sometimes researchers will botch their results to coincide with their hypothesis. This also ensures that both control and experimental groups experience the "placebo effect" more or less equally
What is a double blind crossover study?
I want to know if a medication has the desired effect. I'm going to give half the subjects the 'live' med, and half will get a placebo. The subjects will not know which one they are getting. That's one level of "blind". Studies show that there is a measurable affect based on the fact that the person distributing the med's knows who is getting the med and who is getting the placebo. So I am going to package the med's and give them to the distributing nurse, and the nurse will not know who is getting the med and who is getting the placebo. That is "double blind" model.
A placebo is a medication that elicits a positive emotional response in an experimental subject?
A placebo is used in an experiment as a control. For example, when testing a new medication, experimenters will split the group in two- a control group and an experimental group. The experimental group receives the actual medication, while the control group receives a placebo (in this case, a sugar pill). The placebo will not have any actual effect on the person, but is meant to make sure people aren't making themselves believe that they are cured.
Single blind experiment?
In a double-blind experiment, neither the researchers or the human test subjects know if they are receiving the tested medication or just a placebo (a harmless substance). This eliminates any bias by either the subject (who may psychologically influence his condition) or the experimenter (who may otherwise see effects that are not due to the treatment). While there are logistical and ethical questions that make double-blind experiments difficult, the ultimate aim is to definitively establish whether a drug or treatment actually works.
What is double blind trial?
A double-blind study means that neither the test subject (human) or the researcher administering the study knows whether the test subject is receiving the experimental treatment or the control treatment. Often in human drug tests, the control treatment will be a placebo. This ensures that neither party can make any expectations as to whether they should or shouldn't be seeing results. This is important because sometimes researchers will botch their results to coincide with their hypothesis. This also ensures that both control and experimental groups experience the "placebo effect" more or less equally

The group in an experiment that is not exposed to the tested variable is called the group?
An unexposed subject is the "control" for the experiment. The purpose is to establish an idea of what would normally occur outside the testing procedure. Similarly, in human tests, an inactive "placebo" is given to some subjects to verify that the changes occur independently of the psychosomatic (belief-driven) effects. In a "double blind' experiment, the person distributing the medication also does not know whether any particular individual is receiving the actual drug or a placebo. This is hidden in coded form until the results are recorded.
Does a patient have the right to know they are receiving a placebo?
If you are taking part in a medical or pharmaceutical test, no, you do not. You sign away those rights as a pre-requisite to becoming involved as a test subject. If this was NOT done in a test environment then the doctor would be committing malpractice.
