Question Answer
Research designBasis for determning what data will be collected, and how they will be analyzed and interpreted
(1) Minimizes occurrence of error, (2) Must be determined be determined before research is implemented, (3) It will or will not compromise validity and reliability of the studyA good research design:
Reliabilityconsistency, stability, dependability of the data, reproducitnility, can be utilized again
Validityvalid data are not only reliable but are true and sound, a researcher must use or select a design that will yield a true and accurate information and avoid factors that can invalidate study results
(1) Research design depends on the objective of the study, (2) Non-pre-experimental, (3) True experimental, (4) Quasi experimental designsCommonly used research designs
Non-pre-experimental designAppropriate for descriptive studies
Non-pre-experimental designAppropriate for collecting descriptive information about population or subjects of a study
Non experimental Posttest only/ after-only desogn
Non experimental Pre-test, posttest design
Non experimental Static group comparison
Posttest only/ after-only designAlso called as ONE SHOT SURVEY , because the data are collected only once
Posttest only/ after-only designUsed when the ,objective of the study is to describe a situation/condition of a study population
Posttest only/ after-only designOr used to determine/describe the characteristic of a population/respondents.
Posttest only/ after-only designThere is no baseline data
Posttest only/ after-only designThe design is cheap and easy to conduct
Posttest only/ after-only designResults cannot be conclusive in terms of causality or effect of an intervention
Prestest-post test design or before-after surveyUsed when study wants to know the changes in characteristic (knowledge, attitudes, practices)
Static group comparison2 groups are involved (experimental group and the control group)
Time series designSimilar to the non-experimental design but it repeated 3 times
Non Equivalent Group DesignSimilar to Static Group Design but 2 groups have intervention
Post Test only Control Group designIs also used to determine the effect os an intervention or treatment introduced to a group of subjects (people/objects) as in the pre test post test control group design atleast two groups or areas (ex. Women groups, communities and provinces) with virtually thw same characteristics are chosen and randomly assigned (RA) in the control and experimental group
Post Test only Control Group designNo pretest/pre intervention study is conducted
True Experimental designSubjects are randomly assigned to the experimental group and the control group to achieve pre- intervention equality of the two groups .
(1) Ethical, (2) Capable of obtaining the most reliable and valid data given all possible constraints, (3) Capable of collecting the needed data or measuring whatever it is that happens in the field, (4) Helps an investigator avoid making erroneous conclusionGuidelines for a good research design
randomized experiment generally is the strongest of the three designs when your interest is in establishing a cause-effect relationship.
non-experiment generally the weakest in this respect only to internal validity or causal assessment.
one-shot survey design simplest form of non-experiment
one-shot survey design consists of nothing but a single observation O.
Research method Refers to the techniques that the researcher uses to gather information
Research method design refers to the blue print that you prepare using the research method chose
Research methods focus mainly on data collection,
Research design provides an over all picture of the entire research project
Research methods are loose framework or guidelines from which one has to select one and then apply a research design on that method to achieve desired results
