    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    • Secondary data is taken from published or unpublished materials.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

    • Leading questions, such as "Do you favor the enrolment procedure employed last semester?" can influence respondents to answer in a certain way.
