We call the group interested in studying our “target population. Sampling methods can be broadly classified into two categories: probability sampling and non-probability sampling. It explores both probability and non-probability sampling methods, highlighting their strengths, weaknesses, and appropriate applications. Random sampling is a type of probability sampling where everyone in the entire target population has an equal chance of being selected. The methodology used to sample from a larger population depends on the type of analysis being performed but may include simple random Importance sampling Importance sampling is a Monte Carlo method for evaluating properties of a particular distribution, while only having samples generated from a different distribution than the distribution of interest.
