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 the 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 in mathematics is 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. There is an insufficient basis for assuming equal intervals between adjacent units.
