Final answer:
The measurement of body temperatures in degrees Celsius for newborn babies is an example of an interval scale level of measurement since it allows for ordered differences but no meaningful ratios.
Step-by-step explanation:
Levels of Measurement
The body temperatures in degrees Celsius of a sample of newborn babies is best described using interval scale level of measurement. An interval scale has a definite ordering, and the differences between values can be measured; however, there is no true zero point. In temperature scales like Celsius and Fahrenheit, zero does not represent an absence of temperature, hence a ratio (e.g., twice as hot) is not meaningful. This makes the ratio scale inappropriate, as it requires a true zero point to allow for the comparison of absolute quantities.
For example, a temperature of 40°C is 100°C minus 60°; such differences make sense. But it would not be accurate to say that 80°C is four times as hot as 20°C because temperature scales do not start at an absolute zero where there is no activity. Therefore, when discussing temperature, especially in a context like measuring newborn babies' body temperatures, we refer to an interval scale.
