Survey Design

Survey Design is one of the most important services offered by BioEcoSS Ltd. A strong survey design at the outset of a programme ensures that resources are not wasted by undertaking fieldwork that collects poor quality data. In particular, good survey design includes:

  • Correct formulation of testable hypotheses to answer the questions of interest,
  • Adequate sample size to detect differences between geographical areas or change over time,
  • Appropriate stratification to reduce error variance,
  • Field methods that have high precision and intrinsically low observer variation.

These factors are all closely related to the other services that BioEcoSS offers, so read on to see how they are integrated.
