Do the removal of a mans testicles affect penis size?

Can long distance running affect penis size?
no
How does food affect plant size?
Food affects plant size by it not getting water and if you are putting sugar in it will get small and die.
What is the size of a sample for a survey?
The population is every data point you intend to generalise the survey results to. The sample frame is those data points that you can pick from for the survey. The sample is which of these data points you actually survey, and the sample size is how many of those data points there are. For instance, if you have 700 students in a school, and you have access to 300 of them, and decide to give 30 of them a survey, the sample size is 30.
Why is the second survey more believable than the first?
It is because the sample size for the second survey was larger.
How does sample size affect the experiment?
The sample size determines the accuracy of results in an experiment
What is the sample size of a survey?
The sample size of a survey refers to the number of individuals selected to participate in the survey. It is crucial in determining the reliability and accuracy of the survey results. A larger sample size generally leads to more statistically significant results.
How does sample size affect the margin of error?
The larger the sample size, the smaller the margin of error.
What is least likely to affect the validity of a public opinion poll or survey?
The size of the survey sample is least likely to affect the validity of a public opinion poll or survey, as long as it is conducted randomly. Other factors, such as biased questioning, nonresponse rate, or sampling method, are more likely to impact validity.
How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
What are the elements that affect determination in a sample size?
Margin of error, level of significance and level of power are all elements that will affect the determination of sample size.
How does increasing the sample size affect the sample error of the mean?
It should reduce the sample error.
Is it better to survey as many people as possible.explain?
It is not always better to survey as many people as possible. The sample size needs to be representative of the population being studied to draw accurate conclusions. Too large a sample can be costly and time-consuming, while too small a sample may not provide reliable results. It is important to strike a balance between sample size and representativeness for meaningful survey results.
Why do smaller populations need larger sample sizes?
They do not. Population size does not affect the sample size. The variability of the characteristic that you are trying to measure and the required accuracy will determine the appropriate sample size.
How does the sample size affect an experiment?
Sample size greatly reduces any error to randomness in a given sample. Each experiment requires a proper size of a sample. The better it is fitted to the experiment, the better is the result. For example, if you are trying to find out the study habits of students at your school of 1000 kids, a sample size of 50 would be sufficient. However, if you are trying to find out the study habits of students across the US, a sample size of at least several hundred-thousand would be required, preferably several million.
