RESEARCH METHODOLOGY

Detailed explanation-1: -The variable that is measured by the experimenter is the dependent variable. There are two main variables in an experiment, the independent variable and the dependent variable. The independent variable is what the scientists changes between the groups. The dependent variable is what they measure.

Detailed explanation-2: -There are four levels of measurement for answering quantitative research questions. They are identified as nom-inal, ordinal, ratio, and interval. Ratio and interval levels are very similar, with the exception of a fixed zero point, and so are often referred to as ratioeinterval, giving us only three levels.

Detailed explanation-3: -The foundations of quantitative research are variables and there are three main types: dependent, independent and controlled. The researcher will manipulate an independent variable in an effort to understand its effect on the dependent or controlled variable.

Detailed explanation-4: -Dependent variables are the measured behaviors of participants. They are dependent because they “depend on” what the participants do. The most obvious example is text entry speed, measured, for example, in words per minute.
