Circle the best answer for each question below. There is only one correct answer. There
is no penalty for guessing.
1) A cell phone service provider has 14,000 customers. Recently, the sales department
selected a random sample of 400 customer accounts and recorded the number of minutes
of long distance time used during the previous billing period. The company analyst used
Excel to sort these values in order from high to low. She then assigned the highest value a
rank of 1, the next highest value a rank of 2, and so forth. These ranks would be considered
to be:
a) Ordinal data
b) Nominal data
c) Time series data
d) Interval data
