What is BS 2846-2 - Confidence interval about?
BS 2846-2 is an international standard that specifies the statistical treatment of test results needed to calculate a confidence interval for the mean of a population. The scope of BS 2846-2 is limited to a special question. BS 2846-2 concerns only the estimation of the mean of a normal population on the basis of a series of tests applied to a random sample of individuals drawn from this population and deals only with the case where the variance of the population is unknown. BS 2846-2 is not concerned with the calculation of an interval containing a fixed probability, at least a given fraction of the population (statistical tolerance limits).
Who is BS 2846-2 - Confidence interval for?
BS 2846-2 on confidence interval is useful for:
- Mathematicians
- Statistical analyst
- Data analyst
- Professional statisticians
- Research institution
Why should you use BS 2846-2 - Confidence interval?
Interval estimate has the advantage of supplying a range of values with a known probability of capturing the population parameter. Confidence intervals are used by statisticians to measure the uncertainty in a sample variable. For instance, a researcher may randomly select different samples from the same population and compute a confidence interval for each sample to determine how well it represents the true value of the population variable. The true population mean can be estimated using a confidence interval for the mean.
BS 2846-2 provides its users with information on the field of application, definitions, symbols, estimation of the mean, and the presentation of the results. Using BS 2846-2 guidelines ensures accuracy and better representation of the population.
