## What is maximum variation purposive sampling?

Maximum variation sampling, also known as heterogeneous sampling, is a purposive sampling technique used to capture a wide range of perspectives relating to the thing that you are interested in studying; that is, maximum variation sampling is a search for variation in perspectives, ranging from those conditions that …

## What are the limitations of snowball sampling?

• The researcher has little control over the sampling method.
• Representativeness of the sample is not guaranteed.
• Sampling bias is also a fear of researchers when using this sampling technique.

## Why is purposive sampling appropriate?

Purposive sampling enables researchers to squeeze a lot of information out of the data that they have collected. This allows researchers to describe the major impact their findings have on the population.

## What is maximum variation sampling in qualitative research?

MAXIMUM VARIATION SAMPLING When using a maximum variation sampling method the researcher selects a small number of units or cases that maximize the diversity relevant to the research question.

## What are the sampling techniques in quantitative research?

Methods of sampling from a population

• Simple random sampling. In this case each individual is chosen entirely by chance and each member of the population has an equal chance, or probability, of being selected.
• Systematic sampling.
• Stratified sampling.
• Clustered sampling.
• Convenience sampling.
• Quota sampling.
• Judgement (or Purposive) Sampling.
• Snowball sampling.

The key advantages of convenience sampling are that it is cheap, efficient, and simple to implement. The key disadvantage of convenience sampling is that the sample lacks clear generalizability.

## What is maximum variation?

A maximum variation sample contains cases that are purposefully as different from each other as possible. This type of sampling is useful for examining range in large national or global programs.

## Can you use more than one sampling method?

Most recent answer yes we can , since we can use qualitative and quantitative design so also a combination of sampling techniques is acceptable.

## How is convenience sampling used?

A basic example of a convenience sampling method is when companies distribute their promotional pamphlets and ask questions at a mall or on a crowded street with randomly selected participants. Businesses use this sampling method to gather information to address critical issues arising from the market.

## What is the most accurate sampling method?

Random sampling Finally, the best sampling method is always the one that could best answer our research question while also allowing for others to make use of our results (generalisability of results). When we cannot afford a random sampling method, we can always choose from the non-random sampling methods.

## How do you find the maximum variation?

To determine the maximum theoretical standard variance from an average value specified for a value-bounded set, the squares must be maximized. If the range of values is from pa to pb , and the average value is m , the maximum variance can be calculated fairly simply. Which is simply the product of the two maximum gaps.
