Practical Research II (Part II) Flashcards
research adheres strictly to the procedures of the scientific method. It involves manipulation of variables and employment of a treatment or intervention. Variables in experimental research are isolated, manipulated and controlled for the researcher to determine their effect to the dependent variable. This type of research design is often employed in medical research.
EXPERIMENTAL
research does not use treatment or intervention. It may be classified according to research purpose; descriptive, predictive or explanatory.
NONEXPERIMENTAL
2 kinds of Quantitative Research
Experimental
Non- Experimental
Types of Quantitative Research : 2 Experimental
True - Experimental
Quasi - Experimental
Types of Quantitative Research : 3 Non - Experimental
Descriptive
Predictive
Explanatory
Characterized by rigid manipulation of variables; use of control, selection and random assignment of participants
True Experimental
Characterized by rigid manipulation of variables; use of control but no randomization; intact groups or participants are used instead
Quasi - Experimental
Seeks to describe the current status of an identified variable. Research projects are designed to provide systematic information about a phenomenon. Survey research belongs to this category.
Descriptive
Designed to predict or forecast some event or phenomenon in the future without necessarily establishing cause-and-effect relationship. Correlational research to a certain extent can be classified as predictive
Predictive
Aims to develop or test a theory to explain how and why it operates and to identify causal factors behind the phenomenon
Explanatory
4 Characteristics of Good Research Questions
Feasible
Clear
Significant
Ethical
Consider the amount of time, energy, money, respondents, and even your current situation as a student-researcher. Is the research problem possible? Will it not spend an unreasonable amount?
Feasible
The readers of your study have a uniform agreement as to the meaning of the questions stated. Since your research questions are also considered as the focus in the gathering and analyzing of the data, it is therefore very important that these are stated clearly.
Clear
Ask if your research questions are relevant or important to ask. Will answering these questions provide an additional contribution to address the given research problem? In other words, are the research questions worth investigating? At this point, you do not just consider the time and money that you will spend, but more importantly, the value of what you are trying to investigate. So aside from the reason that your chosen research problem is within your interest, you should also provide a sound justification of your choice as a researcher.
Significant
Always consider the welfare of people, animals, or who so ever involved in your study. Look into ways of answering the research questions without inflicting physical and psychological harm to persons involved.
