(2) types of quantitative research design

• descriptive - it is a design that is exploratory in nature
• descriptive - it is best used when the main objective of the study is just to observe and report a certain phenomenon as it is happening.
• correlational - it seeks to establish an association between variables
• correlational - it does not seek cause-and-effect relationships like descriptive research; it measures variables as it occurs
• Ex Post Facto - the researcher has no control over the variables in the research study. Thus, one cannot conclude that the changes measured happened during the actual conduct of the study.
• Ex Post Facto - if the objective of the study is to measure a cause from pre-existing effects
• quasi-experimental and experimental - identifiable for the existence of treatment or intervention applied to the current research study
• quasi-experimental and experimental - there are two groups of subjects, participants, or respondents
• treatment group - to the group subjected to treatment or intervention
• control group - the group not subjected to treatment or intervention
• quasi-experimental - this research design aims to measure the causal relationship between variables
• quasi-experimental - the effect measured is considered to have occurred during the conduct of the current study
• quasi-experimental - the partiality of this design comes from assigning subjects, participants or respondents into their groups.
• quasi-experimental - the groups are known to be already established before the study, such as age educational background and nationality.
• quasi-experimental - Since the assignment of subjects, participants, or respondents are not randomly assigned into and experimental or control groups, the conclusion of results is limited.
• experimental research - based on the scientific method called experiment with a procedure of gathering data under a controlled or manipulated environment
• experimental research - it's also known as true experimental design since it applies treatment and manipulation more extensively compared to quasi-experimental design
• experimental research - random assignment of subjects or participants into treatment and control group is done increasing the validity of the study.
• experimental research - attempts to affect a certain variable by directly manipulating the independent variable
