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.
When there is as likely a chance that any one member of the population will be selected for participation in a study the sample is considered?
When there is an equal chance for each member of the population to be selected for participation in a study, the sample is considered to be a random sample. This method helps ensure that the sample is representative of the population, reducing bias and allowing for more generalizable results. Random sampling is a fundamental principle in statistical research techniques.
If you want to have a scientifically valid sample for a study you are doing?
To achieve a scientifically valid sample for your study, ensure that your sample is representative of the population you are investigating. This can be done through random sampling methods, which help eliminate bias and improve generalizability. Additionally, determine an appropriate sample size using statistical power analysis to ensure that your findings are reliable. Finally, consider stratifying your sample to account for key demographic variables that may influence the results.
How do sampling methods effect the rigor of a study?
A sample needs to be random and if not a simple random sample of the whole population then a stratified random sample (there are different ways to stratify). Otherwise the study is a waste of time.
Are the results from Alisha's study anecdotal or do they apply to the general population?
To determine if the results from Alisha's study are anecdotal or applicable to the general population, we need to assess the study's methodology. If the study involved a small, non-representative sample and relied heavily on personal experiences, the findings may be considered anecdotal. However, if the study utilized a larger, randomized sample and robust statistical analyses, the results could be more generalizable. Ultimately, the study's design and sample size are critical in establishing its relevance to the broader population.

Acceptable power for a clinical study?
In a clinical study, acceptable power typically refers to the probability of correctly rejecting the null hypothesis when it is false, commonly set at 80% or 90%. This means that there is an 80% or 90% chance of detecting a true effect if one exists. The choice of power affects the sample size required for the study; higher power generally necessitates a larger sample size to ensure reliable results. Adequate power is crucial for the validity and credibility of the study's findings.

Is the study experimental or observational A sample of fish is taken from a lake to measure the effect of pollution from a nearby factory on the fish?
observational
What is he conclusion from research conducted on a sample population to the population as a whole?
Assuming that the population was carefully defined, the sample population was carefully and correctly chosen, and that there were significant results, then the implication is that the results of the study, within the confidence limits indicated, hold true for the population at large.
