Refers to the overall plan and scheme for conducting the study. Thus, the researcher may utilize a historical design, descriptive design or an experimental design
research design
• The purpose of this design is to describe the status of an identified variable such as events, people or subjects as they exist.
descriptive research design
They are also known as longitudinal repeated-measure studies. They are also referred to as interventions, because you do more than just observe the subjects.
It uses the scientific method to establish the cause and effect among a group of variables that make up study.
experimental research design
To collect, verify and synthesize evidence from the past to establish facts that defend or refute your hypothesis.
historical research design
A process of getting information from a proper subset of population.
• The fundamental purpose of all sampling plans is to describe the population characteristic through the values obtained from a sample as accurately as possible.
sampling
Detailed outline of which measurements will be taken at what times, on which material, in what manner, and by whom that supports the purpose of an analysis
sampling plan
• It refers to a sampling techniques in which samples are obtained using some objective chance mechanism.
• They require the use of a sampling frame.
• The probabilities of selection are known.
probability sampling
This technique when there is no way of estimating the probability that each element has of being included in the sample and no assurance that every element has a chance of being included.
non probability sampling
Are the data gathering devices that will be used in the study. It is a testing device for measuring a given phenomenon, such as a paper and pencil test, questionnaires, interviews, research tools, or set of guidelines for observation.
INSTRUMENTS
Refers to the extent to which the instrument measures what it intends to measure and performs as it is designed to perform.
validity
– the extent to which research instrument accurately measures all aspect of a construct.
content validity
the extent to which a research instrument or tool measures the intended construct.
construct validity
the extent to which a research instruments is related to other instruments that measure the same variables.
criterion validity
Relates to the extent to which the instrument is consistent. The instrument should be able to obtain in approximately the same response when applied to respondents who are similarly situated.
reliability
the extent to which all the items on a scale measure one construct.
Internal Consistency/Homogeneity
the consistency of results using an instrument with repeated testing.
Stability or Test-Retest Correlation
consistency among responses of multiple users of an instrument, or among alternate forms of an instrument.
equivalence
known as primary data/raw data. These are data obtained from your own researchers, surveys, observations and interviews.
primary source
known as secondary data. These are data obtained from secondary sources such as reports, books, journals, documents, magazine, internet and more.
secondary source
the researcher asks a standard set of questions and nothing more. The interview follows a specific format with the same line of questioning.
structured interview
most frequently used. It can be conducted in the respondent’s home of workplace, halls or even simply in the street
face to face interview
less consuming and less expensive. The researcher has ready to access to anyone who has a telephone.
telephone interview
is a form of personal interview but instead of completing a questionnaire, the interviewer brings along a laptop or handheld computer to enter the information directly into the database
Computer-Assisted Personal Interviewing
include respondent’s name, address, date of the interview and name of the interviewer.
Respondent’s Identification Data
