question
a new mother keeps track of the time when her baby wakes up each morning. what is the level of measurement of the data?
select the correct answer below:
○ nominal
○ ordinal
○ interval
○ ratio

Explanation:

Interval level data has ordered values with consistent, measurable differences, but no true zero point where the absence of the quantity is meaningful. Morning wake-up time (e.g., 7 AM, 8 AM) fits this: differences between times are meaningful, but a "zero" wake-up time does not represent the absence of waking up. Nominal data is uncategorized labels, ordinal data has ranked but non-measurable differences, and ratio data requires a true zero, which does not apply here.

Answer:

interval
