Another mistake to avoid is failing to account for potential biases introduced by the sampling frame. If the sampling frame is not representative of the population of interest, systematic sampling may lead to biased results. For example, if the sampling frame only includes individuals from certain ...
Sampling allows large-scale research to be carried out with a more realistic cost and time-frame because it uses a smaller number of individuals in the population with representative characteristics to stand in for the whole. However, when you decide to sample, you take on a new task. You ...
Since convenience sampling is hard to replicate with the people, at the same time, in the same circumstances, you can only repeat the research for more insights that add to your original. Therefore, your results should have a section on methodology, explaining that the results were obtained bas...

Choosing a sampling method requires a researcher to consider multiple factors (e.g., the research question, the study methodology, knowledge about the population of interest, the size of the population of interest, the degree of similarity or differences for cases in the population, and time and...
In this study we aimed to: 1. Describe the RDS methodology used in a multi-site consortium of PWUD in rural settings; 2. Evaluate whether the RDS assumptions were met in the seven ROI studies; 3. Compare sample prevalence estimates and RDS-adjusted prevalence estimates; and 4. Compare the...
Moreoever, we expected that this methodology, which could be replicated across cities around the world, would be particularly useful for finding cryptic and potentially undescribed species. Finally, we compare our results with previous published studies on urban ants to illustrate the potential that ...
In our review, we assess the use of so-called non-invasive sampling and summarise which samples can be used successfully when carrying out research on wildlife diseases and health status. Our results show that interest in minimally invasive sampling has steadily increased since the 2010s. Topics ...
Your sampling frame is the company’s HR database, which lists the names and contact details of every employee. Sample size 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. ...
