Standard deviation, σ or s. So if you use an alpha value of p < 0.05 for statistical significance, then your confidence level would be. A confidence interval (ci) is a range of values that is likely to contain the value of an unknown population parameter. Use the standard deviation calculator if you have raw data only.

If you are finding a confidence interval by hand using a formula (like above), your interval is. __% < p < __% d. 24k views 3 years ago.

Me = distance from point estimate to limits of ci: Use the standard deviation calculator if you have raw data only. You can put this solution on your website! That is, we want an interval that is symmetric about the mean. Add two values then divide by two =.118.

__% < p < __% d. Use the standard deviation calculator if you have raw data only. Web this confidence interval calculator is a tool that will help you find the confidence interval for a sample, provided you give the mean, standard deviation and sample size.
