IEc develops statistical sampling plans for a wide variety of applications, including
general population surveys, surveys targeting specialized groups, auditing applications,
and program evaluations.
Sampling plans are customized for every situation, taking into account the
characteristics of the population to be studied, cost factors, and client needs.
Our experience covers a range of sampling approaches, including:
- Simple random sampling;
- Systematic sampling;
- Stratified sampling;
- Multi-stage sampling;
- Cluster sampling; and
- Probability-proportional-to-size sampling.
