Question

Rebecca was asked to measure the number of plastic straws used on the island of Roatan Honduras after their "no plastic straw" campaign. The appropriate measurement scale Rebecca would use is:

a. nominal
b. ordinal
c. interval
d. ratio

Answer 1

Rebecca would use a ratio scale to measure the number of plastic straws used since this scale allows for meaningful calculation of differences and ratios, and it has a natural zero point.

Step-by-step explanation:

The type of measurement scale used when Rebecca was asked to measure the number of plastic straws used on the island of Roatan, Honduras, after their "no plastic straw" campaign would be a ratio scale.

The ratio scale is the appropriate choice because it has a natural zero point (no straws used would be zero), and differences and ratios can be meaningfully calculated with this data.

For instance, if 20 straws were used one day and 40 the next, it is meaningful to say the latter number is double the former.

The ratio scale is the highest level of measurement that provides the most information about the data collected, allowing various statistical calculations, including determining ratios, differences, and ordering the data.
