A sample size is a group which is sampled in surveys, statistics, and in the scientific method. Increasing a sample size might decrease or increase the margin of error, depending on what was being measured. For instance, a sample of 100 women who were pregnant, might increase or decrease the the margin of error for women who showed morning sickness while pregnant.

The width of the confidence interval willdecrease if you decrease the confidence level,increase if you decrease the sample sizeincrease if you decrease the margin of error.

The standard error should decrease as the sample size increases. For larger samples, the standard error is inversely proportional to the square root of the sample size.The standard error should decrease as the sample size increases.

You can't. You need an estimate of p (p-hat) q-hat = 1 - p-hat variance = square of std dev sample size n= p-hat * q-hat/variance yes you can- it would be the confidence interval X standard deviation / margin of error then square the whole thing

Margin of error, level of significance and level of power are all elements that will affect the determination of sample size.

Increase sample size.

The margin of error is reduced.

It should reduce the sample error.

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.

With probability sampling you have no control over the units that are sampled. So the only way to reduce the margin of error is to increase the size of the sample.
