sample codebook.

It's very similar to a Statistical Analysis Plan, actually.

Setup, there is a dogwalking business. It wants to analyze its work.

Raw data is: name of dog, address of owner, time walked, date walked, size of dog (small, medium, or large), health of dog (well or sick) on that date and time, comments, and pay.

The business wants to assign ID# to the dogs, and codewords to the address to make this data anonymous. There isn't anything to do to the comments--since free text is all over the place.

This sample is based on the PROPPR study of blood component ratios in transfusions in trauma patients. Warning: this is complicated.

Experimental design and background: Blood is given to trauma patients as blood components: red blood cells, plasma and platelets. This experiment was aimed at seeing if increasing the ratio of red blood cells over that in normal whole blood would lower mortality. There were two treatment groups, normal and increased red cells. Patients were screened at 12 participating hospitals. Randomization was done by per mutated random blocks, stratified by site.

Raw data: randomization assignment, date and time of admission to the hospital, type of injury, fluids given by EMT/paramedic before admission, hospital, time of blood product administration, lot number of blood product, time of hemostasis achieved, other fluids, pre-existing blood clotting diseases, pre-existing blood clotting inhibito
