A recent comparative analysis of alternative interval estimation approaches and procedures has shown that confidence intervals (CIs) for true raw scores determined with the Score method—which uses the ...

The normal distribution is a continuous probability distribution that is symmetrical, bell-shaped, and centred around its mean. It is one of the most important distributions in statistics because many ...

This article examines the accuracy of normal approximations to confidence limits for the binomial (n,p) parameter p. The method of getting "exact" values from an F table is too slow for practical use ...
