Sentinel site sampling is a surveillance method used to monitor and collect data from specific locations or populations that are representative of a larger area or demographic. This approach allows researchers to gather information on trends, behaviors, or health outcomes while minimizing resource use. By focusing on selected "sentinel" sites, it enables targeted data collection that can be extrapolated to inform broader public health decisions or research findings. It's commonly used in epidemiology and environmental studies to track changes over time.

What difference between Statistical Sampling and non statistical sampling?
an approach to sampling that has the characteristics of being randomly selected and the use of probability theory to evaluate sample results. Whereas non-statistical sampling is therefore any sampling approach that does not have both of the characteristicss of statistical sampling. I hope this will help....
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
What are the sources of sampling errors?
Sampling and Non sampling errors
Which sampling method is generally considered the weakest?
The weakest sampling method is often considered to be convenience sampling. This approach involves selecting a sample based on ease of access rather than random selection, which can lead to significant biases and a lack of representativeness. Consequently, findings from convenience samples may not be generalizable to the broader population, compromising the validity of the research.
What does stratified random sampling represent?
Stratified random sampling is a method of sampling that involves dividing a population into distinct subgroups, or strata, based on specific characteristics, such as age, income, or education level. Researchers then randomly select samples from each stratum in proportion to their presence in the overall population. This approach ensures that different segments are adequately represented, which can lead to more accurate and reliable results in studies. It helps reduce sampling bias and enhances the generalizability of findings.

Difference between classical approach and relative approach of probability with example?
Classical approach has possible outcomes which are known with certainity ie sampling distribution is known. Relative approach is an approach in which probability values are based on historical interest.
What difference between Statistical Sampling and non-statistical sampling?
Statistical sampling is an objective approach using probability to make an inference about the population. The method will determine the sample size and the selection criteria of the sample. The reliability or confidence level of this type of sampling relates to the number of times per 100 the sample will represent the larger population. Non-statistical sampling relies on judgment to determine the sampling method,the sample size,and the selection items in the sample.
What type of website is Start Sampling?

Which sampling method would be best for a large multi-site corporation employee survey?
When carrying out a multi-site corporation employee survey, stratified sampling will give good results. Subsets of the employees, called strata, are used to save time and resources.

The recommended site for arterial blood gas sampling is?
The radial artery is the recommended site for arterial blood gas sampling. It is preferred over other sites like the brachial or femoral arteries due to lower complication rates and easier accessibility.
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.

Answer is Quota sampling. Its one of the method of non-probability sampling.
