What is the Probable Error (PE) used for in the theory of errors?

Measuring the Relative Error (RE) accurately.
Calculating the standard deviation of the mean.
Defining the range within which the most probable value lies.

What does the Probable Error of any single observation (PEs) represent?

The mean of all observations.
The ratio of the error to the measured value.
The range within which the true value lies.
The standard deviation of any single observation. (correct)
