A number of real-life datasets are available for browsing, giving insight as to how Lertap 5 has been applied in a variety of settings. It's possible to download all but one or two of these datasets, providing the chance to experiment with authentic test and survey results -- for instructors, useful class exercises may be built around these datasets.

You don't have to have Lertap 5 running on your computer in order to be able to appreciate and caress the datasets -- all you need is a spreadsheet program, with Excel the most logical (but perhaps not the only) one to use.

Our sample datasets website also has a free Spearman-Brown calculator, and discussions about interfacing Lertap results with SPSS and Xcalibre.

All these wonders may be found by admiring this website.
