Answer :
The recorded annual rainfall in inches for Kawaikini Peak on Kauai is a quantitative continuous variable, reflecting a measurable and variable amount of precipitation that can occur anywhere along a continuous scale. Therefore, the correct answer is option a. true.
The amount of rain recorded for Kawaikini Peak on the island of Kauai, measuring in inches per year, is an example of a quantitative continuous variable. This is because the measurement can take on any value along a continuum within a range, including fractions and decimals, as it represents a measurable quantity that can vary. It contrasts with a quantitative discrete variable, which can only take on specific, separate values, and qualitative variables, which are descriptive and do not have a numeric scale. Therefore, the correct answer is option a. true.
Kauai experiences a significant rain shadow effect due to the height of the mountains, with a sharp distinction between the wet windward side and the semi-desert leeward side. The observation that Kauai is one of the wettest places on Earth with more than 460 inches of rain per year is a quantitative measurement of precipitation and is thus suitably described as a quantitative continuous variable.
