To select random samples in statistics, you can use methods such as simple random sampling, systematic sampling, stratified sampling, or cluster sampling. Simple random sampling involves selecting individuals from a population where each has an equal chance of being chosen, often using random number generators. Systematic sampling selects every nth individual from a list, while stratified sampling divides the population into subgroups and samples from each. Cluster sampling involves dividing the population into clusters, then randomly selecting entire clusters to include in the sample.

In statistics how are random samples selected?
In statistics, random samples are typically selected using methods that ensure each member of the population has an equal chance of being chosen. Common techniques include simple random sampling, where individuals are selected randomly from the entire population, and stratified sampling, where the population is divided into subgroups (strata) and samples are drawn from each stratum. Other methods include systematic sampling, where a starting point is selected randomly and then every nth individual is chosen, and cluster sampling, where entire groups or clusters are selected at random. These methods help to minimize bias and ensure the sample is representative of the population.

Why are random samples so important in Statistics?
Statistics is the science of making effective use of numerical data relating to groups of individuals or experiments sampling is an important to statistics because It deals with all aspects of this including not only the collection analysis and interpretation of such data but also the planning of the collection of data -SDOT15DELEON

How is data collected in statistics?
data can be collected many different ways, but a survey can be cunducted in a few different ways some of them are: simple random, stratified, block samples stratified simple random

Will all random samples from a given population have the same mean?
Data from random samples will not always include the same values. Values are chosen randomly and they may or may not be the same. So means will vary among random samples.

Three reasons why samples are used in statistics?
There are a few reasons why samples are used in statistics. One reason is that the whole population cannot be used and a sample is a good representation of the whole.

What is stratified random sampling in statistics?
Stratified Random Sampling: obtained by separating the population into mutually exclusive (only belong to one set) sets, or stratas, and then drawing simple random samples (a sample selected in a way that every possible sample with the same number of observation is equally likely to be chosen) from each stratum.
