This research does not meet the preliminary standards because there is no manipulation of independent variable therein. The causal-comparative study research is research with groups which have already been formed. Thus this experimental research would involve the use of therapy groups in the experiment rather than random assigning of individuals to investigate conditions. In some cases, the researcher will randomly assign a whole group to treatment and another one to control. In quasi-experimental research the researcher would not randomly allocate subjects to control groups and treatments, i.e., the treatment would not be distributed among the participants randomly. In real experimental research, the researcher would not only manipulate the independent variables but would also randomly assigned individuals to different treatment categories.
In this research, there are numbers of design groups for experiments of which some of them qualify as research analysis while others don’t. The major feature that differentiates this research from other types is that the researcher would be able to manipulate independent variables. The collected data can be used as long as is in numerical form. The data can be gathered here through testing, i.e., a collection of scores in a knowledge test, e.g., an exam or math test.Īdditionally, you can also undertake a psychological test or a survey and questionnaire among other data collection methods where you’ll get numerical responses.
However, it probably would be a waste of time in collecting and analyzing data when there is less reason to think the two variables are related. Theoretically, he can correlate the two quantitative variables as long as he has scores from similar participants. Correlational ResearchĪ correlational study is a research method where a person may have two or more quantitative variables from similar groups of subjects while trying to ascertain whether there is a relationship between the two variables.
