Confidence Interval Mean Calculator. How to calculate a confidence interval. This can be done by summing the entire set of numbers and then dividing by the total numbers in the sample set. Use this Confidence Interval Calculator for the population mean mu in the case that the population standard deviation sigma is not known and we use instead the sample standard deviation s. Sample Mean M.
Confidence Interval For Median Calculator. This interval calculator helps you determine the confidence interval for the population mean based on a sample of observations from that population. This calculator will compute the 99 95 and 90 confidence intervals for the mean of a normal population given the sample mean the sample size and the sample standard deviation. Assuming the following with a confidence level of 95. Enter the mean value and standard deviation value in the given input boxes. Select a confidence level from the list.
Your result will appear at the bottom of the page.
Sample Mean M. Please enter your data into the fields below select a confidence level the calculator defaults to 95 and then hit Calculate. Hypothesis teting can be done using the Hypothesis Testing Calculator. Enter the mean value and standard deviation value in the given input boxes. Sample Mean M. Confidence Interval for Mean Calculator A confidence interval corresponds to a region in which we are fairly confident that a population parameter is contained by.
