Answer:
To avoid the ethical issues a true experiment would cause.
Explanation:
A quasi-experiment is a factual conventional study that is used to calculate the causal effect of interference on a target population without an irregular function. Quasi-experimental research shares closeness with traditional experimental design or randomized controlled trials, but lacks the element of random assignment specifically for treatment or control.
Instead, quasi-experimental designs typically allow the researcher to control the assignment to treatment status, but use some criterion other than random assignment (For example- an eligibility cutoff mark).
One of the example would be C<span>hanging the data to support the hypothesis.
Changing data to support the hypothesis woulld definitely make the studies turn into wrong direction every course of the way.
If the study is being done for mass consumption (such as development of new drugs) , this type of behavior could could cause a lot of health risks to many people (even death)</span>
