Pope (2010) conducted a study to test if noise levels measured in decibels differed in medical/surgical nursing units compared to patient rooms. She found that noise levels were substantially higher in the patient rooms compared to the nursing units. In this study, state whether noise levels in decibels were each of the following:
(a) Continuous or discrete
(b) Qualitative or quantitative
(c) Nominal, ordinal, interval, or ratio scale
