Final Experiment
It seems to imply that the Experiment was only about the Dalek Sec-Diagoras hybrid, not all the humans who are explicitly told they're taken to the Experiment.
These problems might be so great that the article's factual accuracy has been compromised. Talk about it here or check the revision history or Manual of Style for more information.
The "Final Experiment" was an experiment conducted by the Cult of Skaro to create a New Dalek Empire, initiated whilst they were in 1930 Manhattan. The study of the Final Experiment was to see if a Dalek could bond with a human to create a human-Dalek hybrid.
It was headed by Dalek Sec, who also served as the subject. He bonded with the Cult's human liason Mr Diagoras and through a "chromatid solution", the final outcome was the human-Dalek.
