Sampling Methods | Types and Techniques Explained

Published on September 19, dissertation sampling strategy, by Shona McCombes. Revised on April 23, Instead, you select a sample. The sample is the group of individuals who will actually participate in the research. To draw valid conclusions from your results, you have to carefully decide how you will select a sample dissertation sampling strategy is representative of the group as a whole. There are two types of sampling methods:.

You should clearly explain how you selected your sample in the methodology section of your paper or thesis. Table of contents Population vs sample Probability sampling methods Non-probability sampling methods Frequently asked questions about sampling. First, you need to understand the difference between a population and a sampleand identify the target population of your research.

The population can be defined in terms of geographical location, age, income, and many other characteristics. It can be very broad or quite narrow: maybe you want to make inferences about the whole adult population of your country; maybe your research focuses on customers of a certain company, patients with a specific health condition, or students in a single school.

It is important to carefully define your target population according to the purpose and practicalities of your project. If the population is very large, demographically mixed, and geographically dispersed, it might be difficult to gain access to a representative sample, dissertation sampling strategy.

The sampling frame is the actual list of individuals that the sample will be drawn from. Ideally, it should include the entire target population and nobody who is not part of that population. You are doing dissertation sampling strategy on working conditions at Company X. Your population is all employees of the company. The number of individuals you should include in your sample depends on various factors, including the size and variability of the population and your research design.

There are different sample size calculators and formulas depending on what you want to achieve with statistical analysis, dissertation sampling strategy. Probability sampling means that every member of the population has a chance of being selected. It is mainly used in quantitative research. If you want to produce results that are representative of the whole population, dissertation sampling strategy, probability sampling techniques are the most valid choice.

In a simple random sampleevery member of the population has an equal chance of being selected. Your sampling frame should include the whole population. To conduct this type of sampling, you can use tools like random number generators or other techniques that are based entirely on chance.

You want to select a simple random sample of employees of Company X. You assign a number to every employee in the company database from 1 toand use a random number generator to select numbers. Systematic sampling is similar to simple random sampling, but it is usually slightly easier to conduct.

Every member of the population is listed with a number, dissertation sampling strategy, but instead of randomly generating numbers, individuals are chosen at regular intervals.

All employees of the company are listed in alphabetical order. From the first 10 numbers, you randomly select a starting point: number 6. From number 6 onwards, every 10th person on the list is selected 6, 16, 26, 36, and so onand you end up with a sample of people. If you use this technique, it is important to make sure that dissertation sampling strategy is no hidden pattern in the list that might skew the sample.

For example, if the HR database groups employees by team, and team members are listed in order of seniority, there is a risk that your interval might skip over people in junior roles, resulting in a sample that is skewed towards senior employees. Stratified sampling involves dividing the population into subpopulations that may differ in important ways.

It allows you draw more precise conclusions by ensuring that every subgroup is properly represented in the sample. To use this sampling method, you divide the population into subgroups called strata based on the relevant characteristic e.

gender, age range, income bracket, job role. Based on the overall proportions of the population, you calculate how many people should be sampled from each subgroup. Then you use random or systematic sampling to select a sample from each subgroup. The company has female employees and male employees. You want to ensure that the sample reflects the gender balance of the company, so you sort the population into two strata based on gender.

Then you use random sampling on each group, selecting 80 women and 20 men, which gives you a representative sample of dissertation sampling strategy. Cluster sampling also involves dividing the population into subgroups, but each subgroup should have similar characteristics to the whole sample.

Instead of sampling individuals from each subgroup, you randomly select entire subgroups. If it is practically possible, you might include every individual from each sampled cluster. If the clusters themselves are large, you can dissertation sampling strategy sample individuals from within each cluster using one of the techniques above. This method is good for dealing with large and dispersed populations, but there is more risk of error in the sample, as there could be substantial differences between clusters.

Dissertation sampling strategy company has offices in 10 cities across the country all with roughly the same number of employees in similar roles. See an example. In a non-probability sample, individuals are selected based on non-random criteria, and not every individual has a chance of being included. This type of sample is easier and cheaper to access, but it has a higher dissertation sampling strategy of sampling bias, dissertation sampling strategy.

That means the inferences you can make about the population are weaker than with probability samples, and your conclusions may be more limited. If you use a non-probability sample, you should still aim to make it as representative of the population as possible. Non-probability sampling techniques are often used in exploratory and qualitative research. In these types of research, the aim is not to test a hypothesis about a broad population, dissertation sampling strategy, but to develop an initial understanding of a small or under-researched population.

A convenience sample simply includes the individuals who happen to be most accessible to the researcher. You are researching opinions about student support services in your university, so after each of your classes, you ask your fellow students to complete a survey on the topic.

This is a convenient way to gather data, but as you only surveyed students taking the same classes as you at the same level, the sample is not representative of all the students at your university.

Similar to a convenience sample, a voluntary response sample is mainly based on ease of access. Instead of the researcher choosing participants and directly contacting them, people volunteer themselves e. by responding to a public online survey. Voluntary response samples are always at least somewhat biased, as some people will inherently be more likely to volunteer than others. You send out the survey to all students at your university and a lot of students decide to complete it.

This type of sampling, also known as judgement sampling, involves the researcher using their expertise to select a sample that is most useful to the purposes of the research. It is often used in qualitative researchwhere the researcher wants to gain detailed knowledge about a specific phenomenon rather than make statistical inferences, or where the population is very small and specific.

An effective dissertation sampling strategy sample must have clear criteria and rationale for inclusion. You want to know more about the opinions and experiences of disabled students at your university, so you purposefully select a number of students with different support needs in order to gather a varied range of data on their experiences with student services. If the population is hard to access, snowball sampling can be used to recruit participants via other participants.

You are researching experiences of homelessness in your city. You meet one person who agrees to participate in dissertation sampling strategy research, and she puts you in contact with other homeless people that she knows in the area. A sample is a subset of individuals from a larger population. Sampling means selecting the group that you will actually collect data from in your research, dissertation sampling strategy.

For example, if you are researching the opinions of students in your university, you could survey a sample of students. In statistics, sampling allows you to test a hypothesis about the characteristics of a population. Samples are used to make inferences about populations.

Samples are easier to collect data from because they are practical, cost-effective, convenient and manageable. Probability sampling means that every member of the target population has a known chance of being included in the sample. Probability sampling methods include simple random samplingdissertation sampling strategy, systematic samplingstratified samplingand cluster sampling. In non-probability samplingthe sample is selected based on non-random criteria, and not every member of the population has a chance of being included.

Common non-probability sampling methods include convenience sampling, voluntary response sampling, purposive sampling, snowball dissertation sampling strategy, and quota sampling. Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. Have a language expert improve your writing.
