Identifying the measurement scale of data Do women wait longer than men to receive their orders at coffee shops? This question was studied by an econom major at Middlebury College. [Myers, c. K. (2007). Ladies first: A field study of discrimination in coffee shops. Middlebury College Economics Discussion Paper No. 07-11.]
For a sample of customers, data were collected on the following variables:
. Wait Time (in seconds)
· Gender (0 = male; 1 = female)
. Age Group (0 = less than 25; 1-26 to 40, 2 = over 40)
. Order (0 = regular; 1-fancy)
. Appearance (ranked on a scale from 1 to 10)
Recognizing the measurement scale of the data collected on each variable is important because the type of data dictates the appropriate data summary methods and statistical procedures.
Which variablef(s) in the data set are measured using a nominal scale?
A) Gender and Order
B) Age Group and Appearance
C) Gender, Order, Age Group, and Appearance
D) None of the variables
