Question

which is better between the two types of experimental research

Answer 1

Explanation:

Experimental research is any research conducted with a scientific approach, where a set of variables are kept constant while the other set of variables are being measured as the subject of experiment.

Experimental research is one of the founding quantitative research methods.

The simplest example of an experimental research is conducting a laboratory test. As long as research is being conducted under scientifically acceptable conditions – it qualifies as an experimental research. A true experimental research is considered to be successful only when the researcher confirms that a change in the dependent variable is solely due to the manipulation of the independent variable.

It is important for an experimental research to establish cause and effect of a phenomenon, which means, it should be definite that effects observed from an experiment are due to the cause. As naturally, occurring event can be confusing for researchers to establish conclusions. For instance, if a cardiology student conducts research to understand the effect of food on cholesterol and derives that most heart patients are non-vegetarians or have diabetes. They are aspects (causes) which can result in a heart attack (effect).

Answer 2

The answer is 'true-experimental research.'

• There are two types of experimental research- true experimental and quasi-experimental.

• True experimental research takes into concern statistical data and information to prove or disapprove of a hypothesis.

• The quasi-experimental research studies the impacts of an intervention but does not use random participants to represent the entire group.

• The quasi-experimental research has low internal validity, and since true experimental research is based on statistical data, it is more accurate and precise.
