    問題一覧

  • 1

    refers to the device or tool a researcher utilizes to collect the data needed to answer the research questions.

    Instrument

  • 2

    2 Broad Categories of Instruments?

    Researcher-completed instrument Subject-completed instrument

  • 3

    are firsthand, original, and un-interpreted information that comes directly from the source. Examples: Data obtained from primary sources such as autobiography, experiments, theses, census data, bills, account books, etc.

    PRIMARY DATA (RAW DATA)

  • 4

    are existing data that were collected by someone else for a different purpose. Researchers analyze and interpret these pre-existing data for their own research objectives. Examples: Data obtained from secondary sources such as reports, books, journals, documents, magazines, the web, and more.

    SECONDARY DATA

  • 5

    Data Collection Methods -Interviews •structured interview = one where the researcher asks a standard set of questions and nothing more •semi-structured interview •unstructured interview •face-to-face interviews •telephone interviews •computer-assisted personal interviewing (CAPI) Questionnaires •paper-pencil-questionnaires •web-based questionnaires •self-administered questionnaires 2._______ often make use of checklist and rating scales. 3. ________ may make use of recording sheets, checklists, observation guides, and/or field notes. 4.Tests 5.Experiments

    Questionnaire Observations

  • 6

    ______ - refers to the extent to which the instrument (or tool) measures what it intends to measure and performs as it is designed to perform.

    VALIDITY

  • 7

    Major Types of Validity ________ = extent to which a research instrument accurately measures all aspects of a construct Questions to answer: Do the measures (questions, observation logs, etc.) accurately assess what you want to know? Does the instrument cover the entire domain related to the variable, or construct it was designed to measure? A subset of content validity is ______ where experts are asked of their opinion about whether an instrument measures the concept intended.

    Content Validity Face Validity

  • 8

    ________ = the extent to which a research instrument measures the intended/correct construct (trait/attribute/ability/skill) • refers to whether you can draw inferences about test scores related to the concept being studied For example, if a person has high score on a survey that measures anxiety, does this person truly have a high degree of anxiety? Another example is a test of knowledge of medications that requires dosage calculations which instead testing the mathematics

    Construct Validity

  • 9

    ________ = extent to which a research instrument is related to other instruments that measure the same variables

    Criterion validity

  • 10

    Criterion validity is measured in 3 ways: a.___________ – shows that an instrument is highly correlated with instruments measuring similar variables Example: geriatric suicide correlated significantly and positively with depression, loneliness, and hopelessness

    Convergent Validity

  • 11

    Criterion validity is measured in 3 ways: ______ – shows that an instrument is poorly correlated to instruments that measure different variables Example: There should be a low correlation between an instrument that measures motivation and one that measures self-efficacy.

    Divergent Validity

  • 12

    Criterion validity is measured in 3 ways: ______ – means that the instrument should have high correlations with future criterions Example: a score of high self-efficacy related to performing a task that should predict the likelihood a participant completing the task

    Predictive Validity

  • 13

    R______ - the extent to which the instrument is consistent and dependable The instrument should be able to obtain approximately the same response when applied to respondents who are similarly situated. Likewise, when the instrument is applied at two different points in time, the responses must highly correlate with one another.

    Reliability

  • 14

    Main Methods of Testing Reliability: _______ = one wherein the same test is administered twice to the same group of students and the correlation coefficient is determined

    Test re-test method

  • 15

    Main Methods of Testing Reliability: _________ = one in which two forms of the test are constructed with similar but not identical content, type of test item, difficulty and instruction of administration. The parallel forms test is administered to a group of respondents and the paired observation is correlated.

    Parallel or Equivalent Forms Method

  • 16

    A valid instrument is always reliable. However, a reliable instrument is not always valid. True or False?

    TRUE
