Central Limit Theorem: A sampling distribution of the mean is approximately normally distributed if the sample size is sufficiently large. This is true no matter what the population distribution is.

In this article, acceptance sampling plans are developed for the Marshall-Olkin extended exponential distribution percentiles when the life test is truncated at a pre-specified time. The minimum ...

A widely used modification of probability sampling techniques involves the use of quotas at the last level of a multistage area probability sample. Here we analyze an experiment comparing this ...

A discrete distribution is a statistical probability distribution that represents the possible discrete values a variable can take.

The course covers the probability, distribution theory and statistical inference needed for third year courses in statistics and econometrics. Michaelmas term: Events and their probabilities.

Serious polling requires careful data collection and careful adjustment. It doesn't mean much to say your poll is a "probability sample" when your nonresponse rate is 90 percent.
