The researcher aiming to measure physical height in as much detail as possible would employ: a. Ratio level
The ratio level of measurement is the most detailed and precise level of measurement. It possesses all the properties of nominal, ordinal, and interval levels but also includes a true zero point. In the context of height measurement, a true zero point implies that zero height denotes the complete absence or lack of the attribute being measured (height in this case). Ratio level measurement allows for the classification, ordering, measurement of differences between heights, and calculation of ratios, making it the most detailed level of measurement for physical height.
Therefore, option a correct answer.
