What are the sample selection methods in quantitative research? How to determine sample size and sample representativeness?
Best insight from top research papers
Sample selection methods in quantitative research include probability and non-probability sampling techniques. Probability sampling involves selecting a representative sample from the target population, where each member has a known and random chance of being selected. Non-probability sampling techniques, such as convenience sampling, are commonly used due to practical constraints. Determining sample size is crucial for accurate research conclusions. In quantitative research, sample size determination is based on factors such as population size, confidence level, proportion of outcome, and standard deviation. The goal is to achieve an appropriate sample size that provides precise estimates. Sample representativeness is important for generalizability in quantitative research, where the findings can be applied to other contexts. Probability sampling techniques are preferred for health science-related research.

What are sample size recommendations for quantitative studies?5 answersSample size recommendations for quantitative studies vary based on different approaches. Researchers can justify sample sizes by considering factors like resource constraints, power analysis, desired accuracy, heuristics, or acknowledging the absence of justification. It is crucial to understand the factors influencing sample size decisions and review existing rules of thumb while considering sample size determination. Health authorities suggest a minimum power of 80% and a type 1 error of 5% for bioequivalence studies, but reducing sample sizes without affecting scientific validity can save time and resources. Additionally, focusing on achieving narrow confidence intervals for effect sizes can ensure accurate estimation of effects in a study. Researchers should aim for an efficient design balancing precision and efficiency in estimating parameters like intraclass correlation coefficients and standard error of measurements.
How to determine the representativeness of a survey sample?4 answersDetermining the representativeness of a survey sample involves several factors. Probability-based samples are generally more representative than nonprobability samples. Mixed-mode surveys and other-than-Web modes also tend to produce more representative data. Response rate and the number of auxiliary variables used in representativeness assessments are positively associated with representativeness. High response rates are often considered an indicator of representativeness, but low response rates do not necessarily imply low representativeness. Education, as a socio-demographic variable, is commonly used to assess sample representativeness, but inconsistencies in its measurement across surveys make it unsuitable for this purpose. Online data collection strategies can be used, but differences in internet coverage and willingness to participate may introduce differential coverage and nonresponse bias. To address biases, methods such as triangulation with population data sources, combining different types of surveys, and using new methodologies like computer-assisted web interviews can be employed.
What are the different types of quantitative sampling in research studies?3 answersQuantitative research studies use different types of sampling techniques. These include probability sampling and non-probability sampling. Probability sampling methods aim to draw a representative sample from the population and include techniques such as simple random sampling, systematic random sampling, and stratified random sampling. Non-probability sampling methods are used when it is not feasible or practical to use probability sampling. These methods include quota sampling, self-selection sampling, convenience sampling, snowball sampling, and purposive sampling. Researchers often have to make a trade-off between using probability sampling, which allows for generalization of findings, and non-probability sampling, which may be more practical in certain situations. It is important for researchers to carefully consider their research objectives, study scope, and availability of a sampling frame when selecting the appropriate sampling technique.
What is sample in research methodology?3 answersSampling in research methodology refers to the process of selecting a subset of the population of interest for data collection and analysis. It is not always feasible to study the entire population, so a smaller group, known as the sample, is chosen. The sample should be representative of the population to ensure that the findings can be generalized. There are different sampling methods that can be used, including probability sampling and non-probability sampling. Probability sampling involves randomly selecting individuals from the population, while non-probability sampling involves selecting individuals based on the researcher's choice or the population's accessibility. The choice of sampling method depends on the research question and the desired level of generalizability. It is important to clearly mention the sampling method used in the research study to avoid misrepresentation.
What are the main non-probabilistic sampling methods for quantitative research?5 answersThe main non-probabilistic sampling methods for quantitative research include purposive sampling, convenience sampling, quota sampling, self-selection sampling, snowball sampling, and purposive sampling. Purposive sampling involves selecting participants based on specific characteristics or criteria that are relevant to the research question. Convenience sampling involves selecting participants who are readily available and easily accessible. Quota sampling involves selecting participants based on predetermined quotas to ensure representation from different groups or categories. Self-selection sampling involves allowing individuals to voluntarily choose to participate in the study. Snowball sampling involves recruiting participants through referrals from existing participants. Purposive sampling involves selecting participants based on the researcher's judgment and expertise.
What is random sampling method for quantitative studies?1 answersRandom sampling methods for quantitative studies involve the selection of a sample from a population in a systematic way, ensuring that every element of the population has a determinable chance of being included. These methods are used to gather data from a moderately large number of units in a population. They can be a combination of probability random sampling and non-probability sampling procedures. Probability random sampling methods aim to represent the population accurately, while non-probability sampling methods focus on specific purposes of interest. Non-probability sampling is sometimes referred to as outlier sampling. The quality of the generated random numbers in these methods is tested using the histogram method.
