Question

Quizplus · Accepted Answer

Attribute measurement typically involves categorical data and requires a larger sample size to achieve the same level of precision and statistical power compared to variable measurement, which deals with continuous or quantitative data. This is because categorical data have fewer possible values and therefore require a larger sample size to capture the full range of possible responses and minimize sampling error.
