True experimental design is regarded as the most accurate form of experimental research, in that it tries to prove or disprove a hypothesis mathematically, with statistical analysis[3].In a true experimental study, a control and an experimental group are used. In an experiment, data from an experimental group is compared with data from a control group.These two groups should be identical in every respect except one: the difference between a control group and an experimental group is that the independent variable is changed for the experimental group, but is held constant in the control group.

Experimental Study ( Also Known as Intervention Studies ) • Best study design to prove causation. The various stages involved in research are as below. Experimental research is a type of research design in which the study is carried out utilising a scientific approach and two sets of variables. The experimental method involves the manipulation of variables to establish cause and effect relationships. Within-subjects design—a research design in which each participant experiences every condition of the experiment or study. Due to its observational nature, it is often used in descriptive research. Unique Designs 6. Commonly used in sciences such as sociology, psychology, physics, chemistry, biology and medicine .

EXPERIMENTAL RESEARCH It is a systematic and scientific approach to research in which the researcher manipulates one or more variables and controls, and measures any change in other variables The purpose is to study the cause and effect relationship. Experimental and quasi-experimental research can be summarized in terms of their advantages and disadvantages. Advantages 1. do not need as many participants 2. equivalence is certain Simply de ned, the independent. experimental design the researcher introduces the intervention that is assumed to be cause of change and waits until it has produced or has been given sufficient time to produce the change. In pharmacoepidemiology, the primary use of experimental design is in performing clinical trials, most notably randomized, controlled clinical trials. Because the goals of the study rather than the subject's needs determine the exposure assignment, ethical constraints limit the circumstances in- which epidemiologic experi- ments are feasible. Experimental studies do not change trait values, but rather combine (and perhaps interact) with traits to affect the current state. Wait! A. Descriptive research is easy to do in social sciences due to manipulating variables. 3.
