How does the Confidence Interval for the Mean Calculator work?
Free Confidence Interval for the Mean Calculator - Calculates a (90% - 99%) estimation of confidence interval for the mean given a small sample size using the student-t method with (n - 1) degrees of freedom or a large sample size using the normal distribution Z-score (z value) method including Standard Error of the Mean. confidence interval of the mean

What 6 concepts are covered in the Confidence Interval for the Mean Calculator?
- confidence interval
- a range of values so defined that there is a specified probability that the value of a parameter lies within it.
- confidence interval for the mean
- a way of estimating the true population mean
- degrees of freedom
- number of values in the final calculation of a statistic that are free to vary
- mean
- A statistical measurement also known as the average
- sample size
- measures the number of individual samples measured or observations used in a survey or experiment.
- standard error of the mean
- measures how far the sample mean (average) of the data is likely to be from the true population mean
SE = σ/√n
