Principles of Measurement
| Question | Answer |
|---|---|
| Numbers have equal intervals measured from true zero = which level of measurement? | Ratio |
| Numbers have equal interval but no true zero = which level of measurement | Interval |
| Numbers indicate rank order in which level of measurement? | Ordinal |
| Numerals are category labels in which level of measurement? | Nominal |
| What is the lowest level of measurement? | Nominal |
| Consists of categories coded by name, number, letter or symbol though none have quantitative value. Labels for ID. | Nominal |
| Blood type, gender, handedness, type of mental illness and area code are examples of.... | Nominal |
| this measurement scale requires categories to be rank ordered on the basis of an operationally defined characteristic or property. | Ordinal |
| Data are organized into adjacent categories exhibiting a "greater than-less than" relationship. | Ordinal |
| Normal>impaired>absent, none>minimal>moderate>severe, good>fair>poor, are all examples of | Ordinal |
| Manual Muscle Test, funciton, and pn are examples of | Ordinal |
| Calender years, degrees C and F are examples of | Interval |
| What scale possesses the rank-order characteristics of an ordinal scale but also demonstrates known and equal distances between the units of measurement. | Interval |
| What is the highest level of measurement? | Ratio |
| This is an interval scale with a true zero. | Ratio |
| ROM, height, weight, and force are examples of? | Ratio |
| A measure computed for all potential observations in a population is a what? | Parameter |
| A measure computed from actual observations on a sample is a what? | Statistic |
| A measured characteristic of a population is a? | Parameter |
| A measured characteristic of a sample is a? | Statistic |
| Statistical procedures used for estimating population parameters and for testing hypothesis based on population parameters; for use with interval and ration measures. | Parametric Stats |
| Set of statistical procedures that are not based on assumptions about pop parameters; used with nominal and ordinal scales. | Non-parametric Stats |
| The degree to which scores are free from errors of measurement refers to? | Reliability |
| Appropriateness, meaningfulness, and usefulness of data from measurement refers to? | Validity |
