Which level of measurement is exemplified by the following data?"Temperature measurements in degrees Celsius: 20°C, 25°C, 30°C, 35°C"OrdinalNominalRatioInterval

The level of measurement exemplified by the data "Temperature measurements in degrees Celsius: 20°C, 25°C, 30°C, 35°C" is Interval.

Here's why:

1. Nominal level: This is the most basic level of data measurement, which involves assigning data to categories without any order or structure. In this case, temperature measurements are not just categories, they have a specific order and difference between them, so it's not nominal.

2. Ordinal level: This involves categories that have a clear order or ranking. While temperature measurements do have an order (30°C is hotter than 20°C), they also have consistent intervals between them, which makes them more than just ordinal.

3. Interval level: This involves numerical scales where both the order and the exact differences between the values are known. This is the case with temperature measurements in degrees Celsius. The difference between 20°C and 25°C is the same as between 30°C and 35°C.

4. Ratio level: This is similar to interval level, but also has a clear definition of 0. In the case of temperature in degrees Celsius, 0 does not mean the absence of temperature, so it's not a ratio level measurement.

Therefore, the level of measurement for the given data is Interval.
