What is the level of measurement for change in health?

Answer 1

The level of measurement for change in health can vary depending on the specific context and metrics used. Typically, it can be considered an interval or ratio level of measurement if it involves quantifiable changes (e.g., changes in blood pressure or cholesterol levels). If the assessment is based on categories or qualitative changes (e.g., improved, unchanged, worsened), it may be treated as an ordinal level of measurement. Overall, the specific level depends on how the change is quantified or categorized.
