Classify the variable as nominal-level, ordinal-level, interval-level, or ratio-level measurement.
Sizes of beds (twin, full, queen, king)
Interval
O Ratio
Ordinal
O Nominal
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below.
Internet speed levels of "fast," "medium," and "slow"
Choose the correct answer below.
O A. The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless.
O B. The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting point.
OC. The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point.
O D. The nominal level of measurement is most appropriate because the data cannot be ordered.
Exercises
In each of the following exercises, use the ten-step hypothesis testing procedure. For each
exercise, as appropriate, explain why you chose a one-sided test or a two-sided test. Discuss how
you think researchers or clinicians might use the results of your hypothesis test. What clinical or
research decisions or actions do you think would be appropriate in light of the results of your
test?
Ho et al. (A-22) used telephone interviews of randomly selected respondents in Hong
