When working with statistics, OpenOffice.org Calc is handy to calculate a confidence interval. The purpose is to estimate the mean (average) of a population from a sample of the population. As a typical example CNN reported, "63 percent of respondents say [New Orleans] should rebuild" after ...
Confidence intervals demonstrate how sure researchers are that a mean will lie between two numbers. Identify the importance of point and interval...
Conclude: Finish by putting together the estimate and margin of error. This can be expressed as eitherEstimate±Margin of Erroror asEstimate — Margin of ErrortoEstimate + Margin of Error.In the statement of our confidence interval it is important to indicate the level of confidence. This is ...

The Clopper鈥揚earson method allows calculation of classical confidence intervals on the amount of misclassification if data are...
A confidence interval is used in statistics when a range of values, that potentially contains a population parameter, is needed. Using a corresponding z-score, an interval can be calculated. Common confidence intervals of 95% and 99% increase the likelihood that the range of values does contain...
We describe and provide an algorithm for calculating a classical confidence interval on the expected total number of misclassified events from several bins, based on calibration data with the same probability of misclassification on a bin-by-bin basis. Our method avoids a computationally intensive ...
Alternatively, you can use the confidence interval to interpret an odds ratio and draw the same conclusions as using the p-value. If your CI excludes 1, your results are significant. However, if your CI includes 1, you can’t rule out 1 as a likely value. Consequently, your results are...
TYPES OF ANNUITIES Ordinary Annuity: An Ordinary Annuity has the following characteristics: The payments are always made at the end of each interval The interest rate compounds at the same interval as the payment interval For calculating the sum of a series of regular payments the following formula...
