Aims to arrive at numerically expressed laws that characterize behavior of large groups of individuals through the use of variables
Includes one independent variable (IV) and one dependent variable (DV) while the other potentially important variables are controlled.
Independent Variable (IV)
The variable that a researcher actively manipulates, and if the hypothesis is correct, will cause a change in the dependent variable
Dependent Variable (DV)
The measured outcome of a study; the responses of the subjects in a study.
Variables are measured and the relationship between them is quantified. The researcher cannot manipulate any variables.
Relationships between variables are not tested, variables are approached separately. EX. Public Survey
uses data such as interviews or observations. Data evaluation is deeper than quantitative.
the group of people who take part in the research study.
The group of people taking part in the experiment itself. Samples need to be representative of the target population to reflect its essential characteristics.
The degree to which the results of the study can be trusted to reflect the reality.
something that affects the outcome of an experiment and its internal validity.
The extent to which the results of the study can be applied beyond the sample and the settings used in the study itself.
