Standard Deviation or Resolution Error: Which One Should Be Quoted in a Report?

[Max Eilerson]

In a report should I be quoting uncertainties as 2.435(36) m or
2.435 +- 0.036 m. It seems the first way is usually used when quoting a standard deviation error and the second when quoting a resolution error.

That makes sense to me. So, in the report, is the error due to standard deviation (from a sample of data) or is it due to the resolution of the equipment?
