Quantitative Research Designs Flashcards
is defined as the rational and coherent overall strategy that the researcher uses to incorporate all the vital components of the research study. Hence, in order to find meaning in the overall process of doing your research study, a step-by-step process will be helpful to you.
Research design
Quantitative Research Designs have five general classifications:
descriptive research, correlational research, ex post facto, quasi-experimental, and experimental research.
When little is known about the research problem, then it is appropriate to use ___________ research design. It is a design that is exploratory in nature. The purpose of __________ ___________ is basically to answer questions such as who, what, where, when, and how much. So, this design is best used when the main objective of the study is just to observe and report a certain phenomenon as it is happening.
Descriptive Research.
The main goal of this design is to determine if variable increases or decreases as another variable increases or decreases. This design seeks to establish an association between variables. It does not seek cause and effect relationship like descriptive research; it measures variables as it occurs. It has two major purposes: (a) to clarify the relationship between variables and (b) predict the magnitude of the association. However, the extent of the purpose of correlational research depends on the scope and delimitation of the study.
Correlational Research.
If the objective of the study is to measure a cause from a pre-existing effect, then __ ____ _____ research design is more appropriate to use. In this design, the researcher has no control over the variables in the research study. Thus, one cannot conclude that the changes measured happen during the actual conduct of the study.
Ex Post Facto.
pertains to controlling or manipulating the independent variable in an experiment. It is assumed that the changes in dependent variables were caused by the independent variable.
Intervention or treatment
refers to the group subjected to ________ or intervention. The group not subject to _________ or intervention is called the control group.
Treatment group
The term means partly, partially, or almost pronounced as kwahz-eye. This research design aims to measure the causal relationship between variables. The effect measured is considered to have occurred during the conduct of the current study. The partiality of quasi-experimental design comes from assigning subjects, participants, or respondents into their groups. The groups are known to be already established before the study, such as age educational background and nationality. Since the assignment of subjects, participants, or respondents are not randomly assigned into an experimental or control groups, the conclusion of results is limited.
Quasi-Experimental
This research design is based on the scientific method called experiment with a procedure of gathering data under a controlled or manipulated environment. It is also known as true experimental design since it applies treatment and manipulation more extensively compared to quasi-experimental design. Random assignment of subjects or participants into treatment and control group is done increasing the validity of the study. Experimental research, therefore, attempts to affect a certain variable by directly manipulating the independent variable.
