Biostatistics 2

William Weldon, the 19th century British zoologist, was present at the creation of modern biostatistics.  In 1893 he served, with Karl Pearson, on a Royal Committee "For the Purpose of Conducting Statistical Inquiry into the Variability of Organisms."  A year later, he spent considerable time tossing a set of 12 dice more than 26,000 times and recording the results.  Pearson used these data in his paper on the chi-square.

The Institute for Statistics Education at offers courses in a number of topics in biostatistics throughout the year. offers an online courses “Biostatistics 2”. This course covers clinical trial designs including randomized controlled trials, ROC curves, CI and tests for relative risk and odds ratio, and an introduction to survival analysis, and is taught by Dr. Abhaya Indrayan.
