Sampling is the process of selecting a small group from a larger population to gather information and make conclusions about the whole group. It's a practical and cost-effective way to collect data, especially when studying when it is not possible. Sampling is a process used in statistical analysis in which a group of observations are extracted from a larger population. Explore Sampling Methods: Familiarize yourself with different sampling methods, including probability sampling (e.g., random, stratified, cluster) and non-probability sampling (e.g., convenience, purposive, quota). What are the sampling methods or Sampling Techniques? In Statistics, the sampling method or sampling technique is the process of studying the population by gathering information and analyzing that data. It is the basis of the data where the sample space is enormous. There are several different sampling techniques available, and they can be subdivided into two groups. All these methods of sampling may involve specifically targeting hard or approach to reach groups.
