How can reduce the percentage error?
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.

What effect does increasing the sample size have on the probability?
Increasing the sample size generally enhances the accuracy and reliability of statistical estimates. As the sample size grows, the standard error decreases, leading to narrower confidence intervals and greater precision in estimating population parameters. This also increases the likelihood of detecting a true effect if one exists, thereby improving the power of statistical tests. Overall, larger sample sizes reduce the impact of random variation and yield more consistent results.
How to reduce Margin of error?
Increase sample size.
To cut the maximum likely error in half the sample size should be?
... should be increased by a factor of 4. Note that this implies that the only errors are statistical (random) in nature; increasing the sample size won't improve systematic errors.
How do you overcome or reduce the problem of random error and systematic error while doing an experiment-?
You can overcome or reduce the problem of random error and systematic error while doing an experiment by increasing the sample size, which means averaging over a huge number of observations.
How does increasing the sample size affect the sample error of the mean?
It should reduce the sample error.
How are the personal error and random error minimized?
Personal error can be minimized by providing proper training and clear guidelines to the individuals involved. Random error can be minimized by increasing sample size, repeating experiments, and using precise measurement tools.

What is a random sample?
A random sample is a selection from the population of interest where each item (persons, households, widgets, etc.) has an equal chance of being selected. The idea being that measuring a random sample of sufficient size will accurately (within a margin of error) reflect the "true" value that exists in the population - while at the same time reducing your study to a manageable size. A random sample is integral in good survey design to reduce bias in your experiment.
How can you reduce the standard error in research?
Increase n or sample size.
What is the basic requirement for a sample?
The basic requirement for a sample is that it should be representative of the population from which it is drawn, ensuring that the findings can be generalized. Additionally, the sample size should be adequate to provide reliable and valid results, minimizing sampling error. Random selection methods are often employed to enhance the sample's representativeness and reduce bias.

The margin of error is reduced.
