of 10,896establishments from a frame of 52,429establishments. The frame consisted ofall public

49 persons. The sampling for this group involved stratifying establishments into those with 5 to 9
employees and those with 10 to 49 employees. Establishments in these strata were further stratified
on the basis of their economic activities and ultimately a single stage sampling technique was used to
derive representative establishments from each activity using the probability proportion to size (PPS).

Estimates of Sampling Error

Estimates from a sample survey are affected by two types of errors: 1) non-sampling errors and 2) sampling errors. Non-sampling errors are the results of mistakes made in the implementation of data collection and data processing. Numerous efforts were made during implementation of the EES 2017 to minimize this type of error, however, non-sampling errors are impossible to avoid and difficult to evaluate statistically.
