    1. Scales of Measurement Nominal classification labels mutually exclusive exhaustive different in kind, not degree

    2. Scales of Measurement Ordinal rank ordering numbers reflect greater than only intraindividual hierarchies NOT interindividual comparisons

    3. Scales of Measurement Interval equal units on scale scale is arbitrary no 0 point meaningful differences between scores

    4. Scales of Measurement Ratio true 0 can be determined

    5. Contributions of each scale Nominal creates the group Ordinal creates rank (place) in group Interval relative place in group Ratio comparative relationship

    6. Graphing data X Axis horizontal abscissa independent variable

    7. Y Axis vertical ordinate dependent variable

    8. Types of Graphs Bar graph qualitative or quantitative data nominal or ordinal scales categories on x axis, frequencies on y discrete variables not continuous not joined

    9. Bar Graph
