what is the difference between experimental and descriptive research?
258621
Descriptive, correlational, and experimental research designs are used to collect and analyze data. Descriptive designs include case studies, surveys, and naturalistic observation. ... Experimental research involves the manipulation of an independent variable and the measurement of a dependent variable.

Explanatory Research and Descriptive Research The descriptive research uses tools like mean, average, median and frequency. On the other hand, Explanatory research allows the researcher to use the tools which are more qualitative in nature.

Correlational research is the observation of two variables to see if there is a relation between them, being positive or negative. Experimental research is the observation between an introduced variable--the independent variable--under controlled environments and its resulting factor--the dependent variable.

There are three main types of descriptive methods: observational methods, case-study methods and survey methods. This article will briefly describe each of these methods, their advantages, and their drawbacks.

Field research is a research conducted in the real world or a natural setting. ... Participants in a field research may or may not know that they are being studied. On the other hand, controlled laboratory research is a research conducted in a setting specifically designed for research.

Most quantitative research falls into two areas: studies that describe events and studies aimed at discovering inferences or causal relationships. Descriptive studies are aimed at finding out "what is," so observational and survey methods are frequently used to collect descriptive data (Borg & Gall, 1989).

Difference Between Exploratory and Descriptive Research. Exploratory research is one which aims at providing insights into and an understanding of the problem faced by the researcher. Descriptive research, on the other hand, aims at describing something, mainly functions and characteristics.

Qualitative research identifies abstract concepts while quantitative research collects numerical data. But the substantial difference is in the type of action applied and in the size of the sample (respondents).

TYPES OF RESEARCH (based on methodology) QUANTITATIVE RESEARCH Descriptive (What is the current situation?) Experimental (What is the cause?) Ex post facto/Causal comparative (What was the possible cause?)

Descriptive studies only describe the current state of a variable, so there are no presumed cause or effects, therefore no independent and dependent variables. ... Since neither variable in a correlational design is manipulated, it is impossible to determine which is the cause and which is the effect.

Cross-sectional study. ... Cross-sectional studies are descriptive studies (neither longitudinal nor experimental). Unlike case-control studies, they can be used to describe, not only the odds ratio, but also absolute risks and relative risks from prevalences (sometimes called prevalence risk ratio, or PRR).

Pure research refers to systematic study of life aimed at fuller knowledge or a deeper understanding of the theoretical aspects of a phenomenon. ... On the other hand, applied research is a systematic, empirical study undertaken to generate knowledge for problem-solving in a very broad sense.

Descriptive study types include the case report, cases series, and incidence studies. Analytic studies, on the other hand, should be performed if hypotheses exist for risk factors and diseases, and if these hypotheses need to be tested.

In an experimental design, the researcher actively manipulates one or more variables, and in a nonexperimental design the researcher explores relationships or differences among the variables. An experimental design can have a control group, but the control is not manipulated but naturally occurring.

Experimental research is a study that strictly adheres to a scientific research design. It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated and compared. ... The researcher collects data and results will either support or reject the hypothesis.

Experimental Method The key features are control over variables, careful measurement, and establishing cause and effect relationships. An experiment is an investigation in which a hypothesis is scientifically tested.
