The two types of biased sampling methods are convenience sampling and judgmental sampling. Convenience sampling involves selecting individuals who are easiest to reach, which can lead to unrepresentative samples, while judgmental sampling relies on the researcher’s subjective judgment to choose participants, potentially introducing bias based on personal beliefs or preferences. Both methods can compromise the validity of the results by not accurately reflecting the larger population.
There are several types of random sampling, with the most common being simple random sampling, stratified sampling, cluster sampling, and systematic sampling. Simple random sampling gives each member of the population an equal chance of being selected. Stratified sampling involves dividing the population into subgroups and sampling from each subgroup. Cluster sampling selects entire groups or clusters, while systematic sampling involves selecting members at regular intervals from a randomly ordered list.
There are two major alternative sampling plans:

stratified sampling, in which the population is divided into classes, and random samples are taken from each class;cluster sampling, in which a unit of the sample is a group such as a household; andsystematic sampling, which refers to samples chosen by any system other than random selection.

Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability sampling.

Sampling has multiple meanings depending on the domain of work:Statistics - Sampling is selecting a subset of population from within the population to estimate the characteristics of the whole population.There are two different types of Sampling Procedure;1. Probability2. Non ProbabilityProbability sampling methods ensures that there is an equal possibility for each individual in a population to get selected.Non Probability method targets specific individuals.

Two-phase sampling involves selecting initial units from a population through one sampling technique and subsequently selecting final units from the initially drawn units using a different sampling technique. Double sampling, on the other hand, involves selecting two independent samples from the same population, where the second sample is used to check the results of the first sample and make adjustments if needed.
there are two types of data collection: 1. complete/total sampling- all members of the population are measured 2. partial sampling- a proportion of members of the whole population is measured. total enumeration is preferred for certain types of data. it has a high level of accuracy and provides a complete statistical coverage over space and time.
