According to the Scientific Method, in order to make a controlled experiment you NEED to have an hypothesis.
A controlled experiment consists of a test done by a scientist in which only one or a few variables are changed while the others remain constant in order to prove or disprove a hypothesis. This hypothesis is key to said experiment because it provides the starting point from which the professional can begin the procedure, as it helps focus on the subject that one is trying to get results from. Without a clear hypothesis, the outcome of the experimentation will not be valid nor specific.

Becket was born about 1119,[4] or in 1120 according to later tradition.[1] He was born in Cheapside, London, on 21 December, which was the feast day of St Thomas the Apostle. He was the son of Gilbert and Matilda Beket.[note 2] Gilbert's father was from Thierville in the lordship of Brionne in Normandy, and was either a small landowner or a petty knight.[1] Matilda was also of Norman descent,[2] and her family may have originated near Caen. Gilbert was perhaps related to Theobald of Bec, whose family also was from Thierville. Gilbert began his life as a merchant, perhaps as a textile merchant, but by the 1120s he was living in London and was a property owner, living on the rental income from his properties. He also served as the sheriff of the city at some point.[1] They were buried in Old St Paul's Cathedral.
