Study Notes
Scales of Measurement
- In the ordinal scale, both classification and order are present.
- The interval scale provides a measure of the extent to which a person or object possesses some characteristics.
- The ratio scale has a true zero point.
Cognitive Dissonance
- The inconsistency between attitude and behavior is known as cognitive dissonance.
Types of Questions
- Closed-ended questions have specific, limited-alternative responses and ask respondents to choose the one closest to their own viewpoint.
- Open-ended questions allow respondents to answer freely.
Measurement Scales
- The Likert scale provides only two options and is known as a dichotomous scale.
- The category scale indicates attitudes by checking how strongly respondents agree or disagree with statements.
Research Process
- The research process starts with observation.
- The next step after identifying important variables and establishing logical reasoning in the theoretical framework is to conduct surveys.
- A pilot study is a test in which the researcher gives the questionnaire to a few respondents to try out for actual data collection.
Reliability and Validity
- Cronbach Alpha is used to assess the reliability of an instrument.
- The reliability score ranges from 0.5 to 0.9, and a score of 0.8 is considered good.
- A researcher needs to revise or replace an instrument if the reliability score is below 0.7.
- Validity can be measured through several methods like content, criterion, and construct validity.
Research Proposal
- A research proposal is a document that presents a plan for a project.
- The introduction section describes the research participants in detail.
- The literature review section is intended to describe the purpose with a full statement of the research question.
Qualitative Methods
- Qualitative methods are probably the oldest of all scientific techniques.
- The method of qualitative research is depth interview.
Quantitative Problem Statement
- A good quantitative problem statement defines the independent and dependent variables, specifies a research hypothesis, and specifies the relationship between variables.
Research Paper
- A research paper is a brief report of research work based on primary and secondary data.
- The method section of the research plan typically specifies the research participants, design, instruments, and materials for the research study.
