    Study Notes

    Levels of Measurement

    • Nominal scales classify data into categories only
    • Ordinal scales arrange data into categories that have a natural order
    • Interval scales include both nominal and ordinal scales
    • Ratio scales include all properties of interval scales and a meaningful zero point
    • Ratio scales have a true zero point which means that data is not arbitrary
    • Ratio scales allow for a more precise measurement of quantities compared to interval scales

    Mathematical and Statistical Analysis of Scales

    • Discrete measures represent finite, separate categories
    • Continuous measures represent data along a continuous range
    • Discrete measures are often used when categorizing nominal or ordinal data
    • Continuous measures can be used to represent data on interval or ratio scales

    Criteria For Good Measurement

    • Reliability indicates a measurement's consistency
    • Validity refers to a measurement's ability to accurately measure what it is supposed to measure
    • A measurement must be consistent with minimal error to ensure reliability
    • Validity is important to ensure an accurate reflection of the concept being measured

    Techniques for Measuring Attitudes

    • Sorting methods require respondents to categorize concepts based on similarity or other attributes
    • Choice methods ask respondents to select their preferred option from a set of alternatives
    • Both methods are valuable for gathering insights into attitudes, beliefs, or preferences

    Attitude Rating Scales

    • Simple attitude scales classify respondents into two categories typically based on agreement or disagreement with a statement
    • Likert scales allow respondents to indicate their agreement or disagreement with statements using a five-point scale
    • Semantic Differential scales use bipolar adjectives to anchor a seven-point scale for respondents to indicate their feelings
    • Numerical scales use numbers to represent response options, similar to semantic differentials
    • Constant-sum scales require respondents to allocate a fixed number of points across attributes to indicate their perceived importance

    Other Scale Types

    • Graphic rating scales allow respondents to mark a point along a continuous line to represent their attitude
    • Graphic rating scales are flexible but lack standardized answers
    • Behavioral component measures expected future actions towards a specific object
    • Behavioral differentials are similar to semantic differentials and are used to assess behavioral intentions

    Measuring Behavioral Intention

    • Ranking requires respondents to rank order objects based on preference or other attributes
    • Paired comparisons involve presenting respondents with two objects at a time and asking for a preference
    • Paired comparisons require multiple pairwise comparisons when evaluating more than two objects
    • Sorting similarly involves presenting respondents with objects and asking them to categorize them based on similarity

    Measuring Behavioral Intention

    • Sorting methods are used to study respondent preferences, beliefs, or perception of similarity
