Random Sampling
The selection of spatial features or locations at random for unbiased statistical analysis or ground truthing (inferred from standard GIS usage).
How would you define Random Sampling?
A statistical method called random sampling is used to choose a subset of people or data points from a broader population so that each person has an equal probability of being selected. In order to guarantee that the sample is objective and representative of the entire population, this technique is frequently employed in surveys, research, and spatial analysis.
Essential Features:
Unbiased: Every component in the population has an equal chance of being chosen.
Representative: It seeks to capture the traits of the general populace.
Easy and efficient: frequently used as a starting point for more intricate sampling methods.
By guaranteeing that the sample accurately represents the diversity and distribution of the entire dataset or population, random sampling helps minimize bias and improves the validity of inferences made from statistical or spatial data.

Using random sampling techniques, each member of a population is chosen to have an equal probability. Simple, systematic, stratified, and cluster sampling are common forms that guarantee impartial and equitable outcomes.
Every member of a population has an equal probability of being chosen when using the simple random sampling technique. It guarantees the sample's objectivity and representativeness of the total population. Because it is simple to apply and lessens selection bias, which increases the reliability of the data, this approach is frequently employed in surveys and research.
In statistics, random sampling is a technique in which every individual in a population has an equal probability of being chosen for a sample. By lowering bias and ensuring that the sample fairly represents the population, this method makes it possible to draw trustworthy conclusions about the features of the population. It is frequently used to make data-driven decisions in trials, research studies, and surveys.
Using the statistical method of random sampling, every individual in a population has an equal probability of being chosen. For instance, a teacher surveys the study habits of ten pupils chosen at random from a class of fifty. Similarly, to get input on a new product, a business may choose 100 clients at random from its database. This approach guarantees objective portrayal and trustworthy insights.
