A more detailed research, which is often conducted through a survey research form and aims to statistically pin down one or more independent variables to the dependent variable and also tests these relationships for statistical significance is known as descriptive research.
A systematic collection of data from populations or samples of population through use of personal interviews, questionnaire, and other data-gathering devices is termed as survey.
It is often necessary to back up empirical findings from a survey with statistical tests of significance so that the decision makers can have sufficient confidence
in basing their decisions on the researcher's findings.
