A simple random sample is a subset of a statistical population where each member of the population is equally likely to be chosen.

This method works if there is an equal chance that any of the subjects in a population will be chosen. Researchers choose simple random sampling to make generalizations about a population.

Stratified random sampling is a method of sampling that divides a population into smaller groups that form the basis of test samples.

Systematic random sampling controls the distribution of the sample by spreading it throughout the sampling frame or stratum at equal intervals, thus providing implicit stratification. You can use the ...

Random or systematic Random sampling using a quadrat involves the placing of quadrats at random coordinates.

Random or systematic Random sampling using a quadrat involves the placing of quadrats at random coordinates.

A comparison of the three sampling methods shows that stratified random sampling is an efficient method that guarantees a sample which is proportional to the extension of the environmental types. We ...
