Why was the milgram experiment discontinued in the us?

The Milgram experiment was discontinued as it had a number of ethical issues. The most important one was potential harm to the participants. All participants suffered stress, and one even suffered convulsions. While 84% of participants said afterwards that they were glad to have taken part, that still means 16% were unsatisfied, and the major ethical concerns lead to the experiment not being continued.


Why do you have controls in an experiment?

The controls shows the normal state of affairs, so as to allow a comparison with the experiment results, and to help ascertain that the results obtained were due to the factors tested in the experiment, and not a natural occurence/incidence. Having controls in an experiment can thus be said to validate the experiment itself.


What is an experiment in which only one factor is allowed to vary?

A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.


Reference Does wnyonw know which psychologist said that primary school can try a new reading scheme and the effects of it can be compared with a similar school using a different reading scheme It?

This is the following sentence to the above question as I didn't have enough space to write all of it!! It is not a true experiment because the psychologist is unable to manipulate or control variables. It has the advantage thet the participants are unware that they are taking part in an investigation and is certainly not as a laboratoty setting.
