Question

Identify the scaling of each of the following variables. a. Number of bicycles ridden by students in the freshman class. b. Types of bicycles ridden by students in the freshman class. c. The IQ of your teachers (assume equal interval scaling). d. Proficiency in mathematics, graded in categories of poor, fair and good. e. Anxiety over public speaking, scored on a scale of 0-100. (Assume the difference in anxiety between adjacent units throughout the scale is not the same). f. The weight of a group of dieters. g. The time it takes to react to the sound of a tone. h. Proficiency of mathematics, scored on a scale of 0-100. (The scale is well standardized and can be thought of as having equal intervals between adjacent units). i. Ratings of professors by students on a 50-point scale represents half as much assertiveness as a score of 60? Explain.

Explanation / Answer

Quantitative, Ratio. The value 0 is possible.

Qualitative , Nominal . It does not take numeric values

Quantitative , interval scaling. 0 is not defined.

Ordinal scaling. It is ordered.

Interval scaling since the distance between adjacent units is not the same. So o is not the same as numeric zero

Ratio scaling. 0 has meaning.Ratio of two variables have meaning

Ratio scaling. 0 have meaning

Interval scaling as ratio of two values has no meaning

Interval scaling. Ratio of two variables has no meaning
