Website for Datasets - Miles and Shevlin book, "Applying Regression & Correlation"
That page is archived at https://web.archive.org/web/20161024210121/http://www.jeremymiles.co.uk/regressionbook/ , which will take you to https://web.archive.org/web/20160412090429/http://www.jeremymiles.co.uk/regressionbook/data/index.html .
Some of the datasets are available there; I imagine that some others were not crawled. Certainly I successfully obtained data1_1.xls from there. Do feel free to contribute to Internet Archive if you found their service useful.
