Random error and sample size have an inverse relationship...As sample size INCREASES random error DECREASES.

How can reduce the percentage error?
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.
How do you overcome or reduce the problem of random error and systematic error while doing an experiment?
how to reduce the problem of random error and systematic error while doing an experiment
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 does Increasing the sample size while keeping the same confidence level has what effect on the margin of error?
The margin of error is reduced.
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.
Consider a random sample of size 45 from a population with proportion 0.30 find the standard error of the distribution of sample proportions?

The margin of error is reduced.
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.
