Caution: you should really use the standard deviation of the entirepopulation! But you can use the standard deviation of yoursampleif you have enough observations:at least n=30, the more the better. How It Is Calculated The Confidence Interval formula is ...
This Confidence Interval Calculator calculates the confidence interval for group of data, given we have the mean, standard deviation, and sample size for the data unit. The confidence interval allows us to quantify how confident we can feel a group of data is from its mean value. ...
Learn how to use the confidence interval calculator with a step-by-step procedure. Get the confidence interval calculator available online for free only at BYJU'S.
Instatistics, a confidence interval is a range of values from a sample that are likely to contain an unknown population parameter value. Because surveys are often done on a sample of a larger population, there will inevitably be some amount of error or difference between the sample and the fu...
Confidence Interval Calculator by Duplichecker helps you to calculate the population mean from a single sample & you will get value of confidence interval.

A simple definition of the confidence interval is a range of values that has the inclusion of a population parameter. The value of this parameter is unknown. When it comes to the best calculation option, using a confidence interval calculator is the finest alternative. ...
Add and subtract the margin of error from the mean value to obtain the confidence interval. In our case, the confidence interval is between 2.902 and 3.098. That's it! That was quite of a lot of computations, wasn't it? Luckily, our confidence level calculator can perform all of these ...
This calculator will compute the 99%, 95%, and 90% confidence intervals for a predicted value of a regression equation, given a predicted value of the dependent variable, the standard error of the estimate, the number of predictors in the model, and the total sample size. ...
