00:16 Or at least we don't have enough information to determine that conclusively.
00:24 But we have that temperature is typically measured with degrees fahrenheit or degrees celsius.
00:30 If that's the case, then this would be an interval -level measurement.
00:34 But if we had that the temperature was measured in kelvin, which is less common, that would be ratio, because kelvin has a well -defined absolute zero value.
