Why study 1000 when 100 can tell the story?
Sampling means selecting a small part of a population to represent the whole. It saves time, money, and effort while still giving reliable insights.
↳ A good sample mirrors the population, so findings can be generalised.
Probability vs non-probability — know the split.
↳ Probability = random & representative; Non-probability = selective & insight-driven.
Four random ways to pick a sample.
↳ Probability methods give every unit a known, non-zero chance of selection.
Sampling is the process of selecting a small group (sample) from a larger population to study it. Sampling methods are broadly divided into probability (random) and non-probability (non-random) techniques, while qualitat…

What is sampling in research?
BeginnerSelecting a small group from a larger population
Sampling is the process of selecting a small group (sample) from a larger group (population) to study and draw conclusions about the whole.
In probability sampling, every member of the population has:
BeginnerA known, non-zero chance of being selected
Probability sampling requires that every member has a known, non-zero chance of selection, which makes the sample representative.
Which sampling method picks every $k$-th item from a list?
BeginnerSystematic sampling
Systematic sampling selects every $k$-th item, where $k = \text{population} / \text{sample size}$.
A researcher divides a college into arts and science students, then randomly picks some from each group. Which method is this?
IntermediateStratified sampling
Stratified sampling divides the population into strata (groups) and randomly samples from each stratum.
