based on your data and confidence level. The most commonly used confidence level is 95 percent, meaning that there is a 95 percent probability that the true mean lies within the confidence interval you've calculated. To calculate the confidence...

Square the Z-score required for your desired confidence level. For example, if you used a 95 percent confidence level, meaning that you can say with 95 percent certainty that the true proportion will fall in your confidence interval, your Z-score would be 1.96, so you would multiply 1.96 ...
An early criticism of the attitude questions in Michigan's confidence survey was that they did not predict future consumer expenditures at the individual level (Tobin, 1959; Federal Reserve Board, 1955). This criticism seems misplaced today given the widespread use of the confidence indices as ...

For example, if a confidence interval related to the mean of sample data is 10 to 20, and the confidence level is 95 percent, one can be 95 percent certain that the true mean of the population will fall between 10 to 20. How to calculate confidence interval?
Confidence interval definition: a range of values above and below a given statistic, with a specified probability that the true value falls within that range: the span of the interval is equal to twice the margin of error. See examples of CONFIDENCE INTE
