What is Random Sampling?
Random sampling is a method used in statistics to select a subset of individuals or items from a larger population in such a way that each member of the population has an equal and independent chance of being included in the sample. It is a fundamental technique for conducting surveys and experiments.
Random Sampling Definition
Random sampling is a method employed for selecting observations from a population, facilitating generalization about the entire population.
Random Sampling is sometimes referred to as probability sampling, distinguishing it from non-probability sampling. This method encompasses various techniques, including simple random sampling, stratified sampling, cluster sampling, and multistage sampling. However, it should be noted that convenience samples, which are non-arbitrary, fall outside the realm of probability sampling.
Random Sampling Method
Random Sampling is a method of probability sampling where a researcher randomly chooses a subset of individuals from a larger population. In this method, every individual has the same probability of being selected. The researcher aims to collect data from as large a portion as possible of this randomly chosen subset.
In the field of statistics, sampling serves as the technique for selecting a portion of the population to draw statistical inferences. This subset’s characteristics allow us to estimate the attributes of the entire population. In the realm of market research, sampling methods fall into two primary categories: Random or probability sampling and non-probability sampling.
This article discusses the specific category of probability sampling known as random sampling and its types, formulas, advantages, examples, etc.
