Final answer:
The level of measurement for the data on a physician's intake form varies.
Step-by-step explanation:
The level of measurement for the data on a physician's intake form is as follows:
(a) Temperature: Interval scale level. It has a definite ordering, as temperatures can be measured using a numerical scale, but there is no true zero point.
(b) Marital status: Nominal scale level. It is qualitative data that cannot be ordered or used in calculations.
(c) Height: Ratio scale level. It has a definite ordering, the differences can be measured, and it has a true zero point.
(d) Pain level (scale of 0 to 10): Ordinal scale level. It can be ordered, but the differences between the levels cannot be determined accurately.
