Confidence

Synopsis

Analyses the technique of random sampling, used to obtain information about a large population when it is impracticable to examine the entire population. Introduces the idea of confidence intervals, with the testing of audiocassettes for reliability as an example. Through computer animation specifying a probability model for distribution of unreliable cassettes with an unknown parameter, shows how varying the parameter affects the probability of different sample proportion.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
