Study Notes
Disadvantages of Interview Methods
- Face-to-face interviews have a disadvantage of social desirability bias, where respondents may provide false information to impress the interviewer.
- Telephone interviews have a disadvantage of lack of nonverbal cues, making it difficult to interpret respondents' reactions.
- Computer-assisted personal interviewing (CAPI) has a disadvantage of technical issues, such as equipment malfunctioning or poor internet connectivity.
Disadvantages of Questionnaires
- Paper-pencil questionnaires have a disadvantage of data entry errors, which can occur when transferring responses to a digital format.
- Web-based questionnaires have a disadvantage of validity concerns, as respondents may not be who they claim to be, and may bias the results.
Data Collection Methods
- Measuring characteristics like height is best done using direct measurement methods.
- Open-ended questions allow for free responses, where respondents can provide detailed and qualitative answers.
- Probability sampling utilizes random selection to ensure a representative sample.
Data Types
- Primary data is collected from original sources and is first-hand in nature.
- Secondary data is taken from published or unpublished materials.
Research Concepts
- Sampling is the process of selecting samples from the population.
- The population is the entire group that the researcher is interested in.
- Neutral questions must not be worded in a manner that will influence the respondent to answer in a certain way.
- Experimental designs are used when the objective of the study is to determine the cause and effect of certain phenomena or event.
- Non-probability sampling avoids any form of random selection.
Question Characteristics
