Confidence interval In statistics, a confidence interval is a type of estimate computed from the statistics of the observed data. This gives a range of values for an unknown parameter. The interval has an associated confidence level that gives the probability with which the estimated interval will contain the true value of the parameter. The confidence level is chosen by the investigator. For a given estimation in a given sample, using a higher confidence level generates a wider confidence interval. Wikipedia

Binomial proportion confidence interval In statistics, a binomial proportion confidence interval is a confidence interval for the probability of success calculated from the outcome of a series of successfailure experiments. In other words, a binomial proportion confidence interval is an interval estimate of a success probability p when only the number of experiments n and the number of successes nS are known. Wikipedia

Confidence Intervals A confidence interval Often, this parameter is the population mean , which is estimated through the sample mean . If he knows that the standard deviation for this procedure is 1.2 degrees, what is the confidence Since the sample size is 6, the standard deviation of the sample mean is equal to 1.2/sqrt 6 = 0.49.

Confidence intervalIn most circumstances, providing someone with an estimate without giving them some idea of how accurate your estimate really is might not be helpful. If you ask me how heavy is a typical adult male African elephant, I could tell you that I think the answer is about 12,000 pounds and that would be helpful. However, if I tell you that the answer is 12,000 pounds plus or minus 500 pounds, that means something very different than if I tell you that it is 12,000 pounds plus or minus 5 pounds. So that's the first big idea with a confidence interval It gives you a range of values for the estimate rather than a single value so you have an idea of how precisely the estimate has been made. But there is a second big idea with confidence It arises because in statistics, the random modeling makes it impossible to be certain that your estimate is correct even when you provide a range as previously discussed . There's always some small chance that the data you used to build the

Confidence intervalConfidence Interval - an overview | ScienceDirect Topics A confidence interval is defined as the range of values that we observe in our sample and for which we expect to find the value that accurately reflects the population. Confidence Interval I G E for a Mean. The following example demonstrates how to calculate the confidence confidence ^ \ Z level for this example, we assume the distribution is approximately normal . Of course, confidence ^ \ Z intervals can be quite large, depending on the size of the sample and the standard error.
