Sampling

In this section, we will discuss sampling in statistics.

Population

Population refers to the entire set of individuals or items that we are interested in studying. It can be finite or infinite, and it can consist of people, animals, plants, or any other entities.

Sample

Sample refers to a subset of individuals or items selected from the population. The sample should be representative of the population.

Sampling

Sampling is the process of selecting a subset of individuals from a population to estimate characteristics of the whole population.

We need to select a sample that is representative of the population to make valid inferences without using the entire population. This is important because it allows us to make conclusions about the population without having to study every individual which is resource-intensive and time-consuming.

Sampling Size Selection

This is an interesting topic in statistics as right choice of sample size is crucial for obtaining accurate and reliable results.

A sample that is too small may not accurately represent the population, while a sample that is too large may be unnecessarily costly and time-consuming.
