There is a general misconception around research that once the research is non-experimental, then it is non-scientific, making it more important to understand what experimental and experimental research entails. Experimental research is the most common type of research, which a lot of people refer to as scientific research. Non experimental research, on the other hand, is easily used to classify research that is not experimental.
Advantages and Disadvantages of Experimental Research: Quick Reference List
Quantitative research is the process of gathering observable data to answer a research question using statistical , computational, or mathematical techniques. It is often seen as more accurate or valuable than qualitative research, which focuses on gathering non-numerical data. Qualitative research looks at opinions, concepts, characteristics, and descriptions. Quantitative research looks at measurable, numerical relationships. Both kinds of research have their advantages and disadvantages. Research benefits small businesses by helping you make informed decisions.
A quasi-experiment is an empirical interventional study used to estimate the causal impact of an intervention on target population without random assignment. Quasi-experimental research shares similarities with the traditional experimental design or randomized controlled trial , but it specifically lacks the element of random assignment to treatment or control. Instead, quasi-experimental designs typically allow the researcher to control the assignment to the treatment condition, but using some criterion other than random assignment e. Quasi-experiments are subject to concerns regarding internal validity , because the treatment and control groups may not be comparable at baseline. In other words, it may not be possible to convincingly demonstrate a causal link between the treatment condition and observed outcomes. This is particularly true if there are confounding variables that cannot be controlled or accounted for.

Experiments and Quasi-Experiments
An experiment is a study in which the researcher manipulates the level of some independent variable and then measures the outcome. Experiments are powerful techniques for evaluating cause-and-effect relationships. Many researchers consider experiments the "gold standard" against which all other research designs should be judged. Experiments are conducted both in the laboratory and in real life situations. True experiments, in which all the important factors that might affect the phenomena of interest are completely controlled, are the preferred design. Often, however, it is not possible or practical to control all the key factors, so it becomes necessary to implement a quasi-experimental research design. In an experiment, the researcher manipulates the factor that is hypothesized to affect the outcome of interest.

Quantitative methods help researchers of different stripes gather data on a variety of subjects. Researchers must choose their methods carefully, however, as one type of quantitative method design may not suit all types of research. Some research requires a design which includes no applied treatment, experiment or anything that otherwise interferes with the subject of the research.

European Journal of Training and Development , v40 n p Purpose: Nonexperimental research, defined as any kind of quantitative or qualitative research that is not an experiment, is the predominate kind of research design used in the social sciences. How to unambiguously and correctly present the results of nonexperimental research, however, remains decidedly unclear and possibly detrimental to applied disciplines such as human resource development. To clarify issues about the accurate reporting and generalization of nonexperimental research results, this paper aims to present information about the relative strength of research designs, followed by the strengths and weaknesses of nonexperimental research.
Голос шефа из смешливого вдруг стал жестким: - Сьюзан, я звоню потому, что ты нужна мне. Срочно. Она попыталась собраться с мыслями. - Сегодня суббота, сэр. Обычно мы… - Знаю, - спокойно сказал. - Но ситуация чрезвычайная. Сьюзан встала.
Стратмор стукнул кулаком по столу. - Я должен был знать. Да взять хотя бы его электронное имя. - Боже мой, Северная Дакота.
Коммандер, - возразила она, - Танкадо отлично понимал, что АНБ может найти его переписку в Интернете, он никогда не стал бы доверять секреты электронной почте. Это ловушка. Энсей Танкадо всучил вам Северную Дакоту, так как он знал, что вы начнете искать. Что бы ни содержалось в его посланиях, он хотел, чтобы вы их нашли, - это ложный след.
Клянусь, что я тебя пальцем не трону. Сьюзан пыталась вырваться из его рук, и он понял, что его ждут новые проблемы.
