Using the Population Survey Tool
A confidence interval is a range of values that’s likely to include a certain value. A 95% confidence interval means the range will include the true value of that number 95% of the time.
The standard error of a mean approximates the standard deviation of a population mean based on a statistical sample of that population. It measures how much discrepancy is likely to be in the sample mean relative to the true population mean.
