Some considerations are:
- large samples take more time and money to process
- if the characteristic of interest is very variable then a large sample is required for accurate estimates
- if the characteristic of interest is very rare in the population then a large sample is required to ensure that units with that characteristic are included in the sample
- the greater the accuracy required of the estimates based on the sample, the larger the sample required.

What are the sample size and its determinants?
Sample size refers to the number of observations or participants included in a study or survey. Determinants of sample size include the desired level of statistical power, effect size, significance level (alpha), population variability, and the research design. Larger sample sizes generally increase the reliability and generalizability of results, while smaller sizes may lead to higher sampling error and less confidence in findings. Researchers must balance practical considerations, such as time and cost, with the need for sufficient sample size to achieve meaningful results.
What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
Does sample size affect survey result?
Yes, sample size can significantly impact survey results. A larger sample size generally provides more representative and reliable results compared to a smaller sample size. With a larger sample size, the margin of error decreases, increasing the accuracy of the findings.
What is the difference between sample size and sample unit?
sample size is the specific size of a thing like the how long or wide. while sample unit is the whole thing not referring to specific number size.
What is the sample size definition?
Sample size is the number of samples arawn from a population. If you drew 20 samples, your sample size would be 20.
What sample size of a population of 200 is most likely to give a reliable conclusion?
For a population of 200, a sample size of around 30 to 50 individuals is often considered sufficient to draw reliable conclusions, as it balances the need for statistical power with practical considerations. This range allows for a good representation of the population while minimizing the margin of error. However, if more precision is required, a larger sample size closer to 100 can enhance reliability. It's also important to ensure the sample is randomly selected to avoid bias.

Will margins of error for sample of size 80 be larger or smaller than those for sample size of 40?
They should be smaller for the sample size 80.

In basic statistics what is sample size and effective sample size?
sample size refers to the collection of data by only a selected size of te population through the process of sample surveys and sampling methods used in collecting data.
What is the sample size for a population of 60010?
well a sample size can be any size depending on the requirements. A sample size could be 10 people of that entire population or it could be 1000 people.
