RESEARCH METHODOLOGY

Detailed explanation-1: -Experiments done in a laboratory will almost certainly be quantitative. In a health care context, randomised controlled trials are quantitative in nature, as are case-control and cohort studies. Surveys (questionnaires) are usually quantitative .

Detailed explanation-2: -There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research. attempts to establish cause-effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences.

Detailed explanation-3: -Quantitative research requires varying degrees of control, ranging from minimal control to highly controlled, depending on the type of study (Table 3-1).

Detailed explanation-4: -Quantitative Data: Quantitative data are data for which the scale of measurement has magnitude and is either interval or ordinal. Quantitative values are continuous, so each possible value may be greater or less than any other value.
