    It not a true experiment, not at all use.

    Explanation:

    A true experiment is a type of experiment that is thought to be the most accurate type of experimental research. The true experiment supports the hypothesis using statistical analysis. We can be called that true experiment is the only experiment that works on cause and effect relationships.

    There would be a criterion for a true experiment: There would be a control group and experimental group. Researchers manipulated variables. Random assignment

    Example of the true experiment:

    There is an example of placebo effects. There was two groups such as a control group and an experimental group. The control group received a placebo, that looks like medicine, not exactly a medicine. the people were just because they think they are receiving treatment. If the control group more reduction in anxiety than the experimental group then we can say that the placebo effect and reduction in anxiety are not caused by the drug.
