UPDATING THE GANZFELD DATABASE

Essa tabela foi extraída de Bem, Palmer, Broughton, 2001, Updating the Ganzfeld Database: a Victim of Its Own Success? Atenção que a coluna "p value" foi criada e calculada por mim a partir do z score, usando os recursos disponíveis em: http://www.fourmilab.ch/rpkp/experiments/analysis/zCalc.html. Como meu conhecimento de estatística é fraquíssimo, pode haver erro nisso.
