These 10,000 students are our population (N). That’s why it is one of the most affordable options of information gathering that exists right now. The students enrolled in the introductory sociology class, for example, might be mostly first-year students. Samples drawn from population are used by researcher for making statistical inferences and estimating the information about whole population. When a researcher is eager to begin conducting research with people as subjects, but may not have a large budget or the time and resources that would allow for the creation of a large, randomized sample, she may choose to use the technique of convenience sampling. Bias. It is challenging to replicate the results of convenience samples. It doesn’t take much effort to start a convenience sampling effort. You intended to collect your data using a survey. 1. The convenience sample may help you gathering useful data and information that would not have been possible using probability sampling techniques, which require more formal access to lists of populations [see, for example, the article on simple random sampling]. This work wants to find specific feedback points or data on specific subjects to help gain new perspectives about products, services, or ideas. Commerce Mates is a free resource site that presents a collection of accounting, banking, business management, economics, finance, human resource, investment, marketing, and others. The advantages and disadvantages of random sampling show that it can be quite effective when it is performed correctly. Sampling also have some demerits. When researchers decide to use convenience sampling, then they often describe how their data collection methods would differ from an ideal, randomly selected sample. Convenience sampling is vey easy to carry out with few rules governing how the sample should be collected. 7. Convenience sampling is a type of non-probability sampling technique. You can post a survey link to a social media page, ask questions in a public space, or have a poll in which people can vote online. This issue creates interference problems with statistical analysis. If a research only covers a small part of the population, this method can be used accordingly. Convenience sampling are useful. This sampling technique may be more appropriate for one type of study and less for another. Surveys can even get tailors to help provide more details about an individual’s demographic profile so that it becomes possible to build generalizations about a larger group in the future. While the results of studies using convenience samples may not necessarily be applicable to the larger population, the results could still be useful. Advantages of Sampling. Some of the advantages are listed below: Every coin has two sides. Disadvantages of Convenience Sampling Even though convenience sampling can be easy to obtain, its disadvantages usually outweigh the advantages. In our example of the 10,000 university students, we were only interested in achieving a sample size of 100 students who would take part in our research. It will not exactly reflect the position or characteristics of the town but it is still reflecting some major characteristics to some extent. Convenience sampling is used for our ease as it's less time consuming and easier method. This research method saves time when gathering data. By using sampling, you can get detailed information on the data even by employing small amount of resources. Convenience sampling is an affordable way to gather data. Probability and non-probability sampling are two common sampling methodologies. The items in the colored square represent the items chosen as samples. Did others take part out of kindness or because they had a particular grievance with the organisation? Convenience sampling is a type of Non-probability Sampling. One advantage of convenience sampling is that data can be collected quickly and for a low cost. Notations about potential bias can improve the validity of the work. If there isn’t a description of the methodology used to gather data, then trusting its reliability shouldn’t be the first priority. Whilst a probability sampling technique would have been preferred, the convenience sample was the only sampling technique that you could use to collect data. The Different Types of Sampling Designs in Sociology, Convenience Sample Definition and Examples in Statistics, Understanding Stratified Samples and How to Make Them. It is also essential to avoid judgment when conducting research. One disadvantage of convenience sampling is that subjects in a convenience sample may not be representative of the population the researcher is interested in studying. Sampling saves time to a great extent by reducing the volume of data. Was it because some employees were simply too busy? Although you can get pieces of authentic feedback, it is up to the researcher to determine if the information is useful. However, if the issue covers a whole country or a global audience, convenience sampling is not a very … For example, researchers Joe Henrich, Steven Heine, and Ara Norenzayan found that psychology research studies often involve American college students, who tend to be unrepresentative of the global population as a whole. It even allows for the completion of multiple studies simultaneously or in an expeditious manner since one participant can provide data on multiple subjects in just a few minutes when using this method. These convenience sampling advantages and disadvantages provide an overview of this qualitative research effort. Fails to represent the whole population. Even if you want to rent a contact list to have more specificity with your contact efforts, the price is usually less than $1,000. It could also mean surveying friends, students, or colleagues to which the researcher has regular access.. We can say that the sample correctly represents the population because the ration of white:grey:black is the same in the sample as in the population. Almost all forms of convenience sampling involve collecting data from the on-hand population. The usual approach taken with this method involves the creation of a questionnaire that gets distributed to the targeted group. A convenience sample is simply one where the units that are selected for inclusion in the sample are the easiest to access. Dependence in convenience sampling means that the sample items have connections to each other in some way. If researchers outsource this task, then they have zero control over this issue. People will say what they feel is necessary to extract themselves from that situation. Several convenience sampling advantages and disadvantages are worth reviewing when looking at this form of data gathering. When researchers don’t have a need to obtain accurate sampling, then the grab method allows them to collect data before moving on to the other aspects of their study. Consequently, Henrich and his colleagues suggest, study results could look different if researchers studied non-students or individuals from non-Western cultures. Researchers that perform convenience sampling soon find out that the average person doesn’t want to speak with them or fill out an online survey. Even though convenience sampling can be easy to obtain, its disadvantages usually outweigh the advantages. It only takes a few minutes of time to get rich info about specific topics. Researcher bias can enter into the sampling technique. Each person has a unique set of priorities and perspectives that cannot be predicted since there isn’t a qualification standard beyond agreeability with this process. One disadvantage highlighted by the above example is that a convenience sample is not representative of all college students, and therefore the researcher would not be able to generalize her findings to the entire population of college students. You decide to spend the two days at the entrance of the organisation where all employees have to pass through to get to their desks. Let?s say that the university has roughly 10,000 students. What Is Transnationalism? Although you do not subject all the data to your queries, the chance that you get the desired results is almost similar to that when you do thorough checking. Application of certain queries to less than 100% of the population(group of all items that we are trying to observe and analyze) is known as Sampling. It doesn’t take much effort to start a convenience sampling effort. What their data cannot pick out are the differences that exist between the multiple subgroups. Several convenience sampling advantages and disadvantages are worth reviewing when looking at this form of data gathering. The selected pattern is termed as sample which is a small and manageable version of large set of data. Sampling is most widely used in statistical testing where size of population is too large such that it is impossible to include each individual observation in test. This advantage makes it much easier for researchers to meet their data quotas quickly. 2. Convenience sampling is vey easy to carry out with few rules governing how the sample should be collected. It is useful as an intervention to correct dissatisfaction. The sample may be unrepresentative in other ways, such as by religiosity, race, class, and geographical region, depending on the population of students enrolled at the school. Irrespective of the disadvantages (limitations) of convenience sampling, discussed below, without the use of this sampling technique, you may not have been able to get access to any data on employee satisfaction in the organisation.
