Sampling

Selection of a finite sample from a group of people or things that is representative of the group to which it belongs, in order to estimate and study its characteristics and extrapolate them to the entire population.
 
In the field of Human Resources, sampling is used to analyse information from part of the workforce without having to collect data from every person in the organization. It enables organizations to conduct employee engagement surveys, workplace climate studies, satisfaction surveys, and research into different aspects related to the employee experience.
 
The main types of sampling include:
  • Random sampling: each person in the population has the same probability of being selected.
  • Stratified sampling: the population is divided into groups with common characteristics, and a sample is selected from each of them.
  • Convenience sampling: participants are selected based on their availability or accessibility.
