in a study, the data you collect is temperature in celsius.
what is the level of measurement?
nominal
ordinal
interval
ratio

Explanation:

To determine the level of measurement for temperature in Celsius:

• Nominal: Categories with no order (e.g., colors), not applicable here.
• Ordinal: Ordered categories with no fixed interval (e.g., rankings), not applicable.
• Interval: Data with ordered values, equal intervals, but no true zero (0°C does not mean no temperature). Celsius temperature has equal intervals (e.g., difference between 10°C and 20°C is same as 20°C and 30°C) and no true zero (0°C is a defined point, not absence of temperature), so it fits interval.
• Ratio: Requires true zero (e.g., weight, length), which Celsius lacks.

Answer:

C. interval
