Confidence intervals give us a range of plausible values for some unknown value based on results from a sample. This topic covers confidence intervals for means and proportions. Our mission is to provide a free, world-class education to anyone, anywhere. Confidence Intervals. A confidence interval (or confidence level) is a range of values that have a given probability that the true value lies within it. Effectively, it measures how confident you are that the mean of your sample (the sample mean) is the same as the mean of the total population from which your sample was taken (the population mean). A confidence interval is a range of values that is likely to contain a population parameter with a certain level of confidence.

Confidence interval

Mean overall survival was 39.5 months (95% confidence interval [CI]: 28.1-51.0) and mean progression free survival was 36.5 months (95% CI: 25.7-47.2).

Confidence interval

A confidence interval is an estimate of an interval in statistics that may contain a population parameter. The unknown population parameter is found through a sample parameter calculated from the sampled data. For example, the population mean μ is found using the sample mean x̅. Confidence Intervals.

Confidence interval

Confidence interval = sample mean ± margin of error. The population mean for a certain variable is estimated by computing a confidence interval for that mean. If several random samples were collected, the mean for that variable would be slightly different from one sample to another.

The Confidence Interval is based on Mean and Standard Deviation. Its formula is: X ± Z s√n. Where: X is the mean; Z is the Z-value from the table below ; s is the standard deviation; n is the number of observations The confidence interval (CI) is a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed as a % whereby a population mean lies between an upper and lower interval. A confidence interval is an estimate of an interval in statistics that may contain a population parameter. The unknown population parameter is found through a sample parameter calculated from the sampled data. For example, the population mean μ is found using the sample mean x̅.
