Interpret measurement uncertainty

Fictional general training exercise. The marker and survey line are the same. The stated ±2 m is a conservative uncertainty bound for each reading, not a probability distribution.

Resource description

The marker and survey line are the same. The stated ±2 m is a conservative uncertainty bound for each reading, not a probability distribution.

1. Calculate the apparent retreat distance in metres.

2. Using conservative worst-case bounds, what is the combined uncertainty bound on the difference, in metres?

3. Does the apparent change demonstrate retreat beyond these uncertainty bounds?

The maps and data are fictional. These exercises do not count as required fieldwork.
