Error theory as an exam actually tests it: systematic versus random error, standard deviation, propagation through sums and products, weights, and closure tolerances.
What this subject area expects
Compute the mean, standard deviation and standard error of a set of observations
Propagate random error through a sum, a series and a product
Form weights from standard deviations and compute a weighted mean
Judge a traverse or level loop against a stated tolerance
