To celebrate, it has been given cosmetic surgery, i.e. a Windows interface. All the familiar features remain. As further procrastination they commission a sample survey to estimate the mean of a single variable, the u-shaped distribution of attitude toward redevelopment. One chooses the number of clusters and then the total sampling proportion. One chooses the overall sampling proportion, which is then applied to each stratum.
Results appear for the three strata and the total sample.
For each simulation the user receives means, medians, standard deviations, etc. A separate command gets the true result. The population mean is 3.172 with a standard deviation of 1.654. The program is accompanied by extensive on-line Help information including the equivalent of a chapter on sampling in an introductory text. All this has been translated from DOS to Windows by John McLoughlin, building on Nigel Gilbert's original DOS version.
