• The Titanic hit an iceberg on April 14, 1912, at 11:40 p.m. and sunk completely about 2 hours and 40 minutes later.
• A total of 2207 individuals were on board at the time of the collision and only 710 survived, despite the fact that the lifeboats could have saved 1178, so they had been used at only 60% of their capacity.
• The survival rates of individuals differed greatly according sex, classes, and types of crew.

Hypothesis 1: sex contributed to individuals who survived on the titanic?

hypothesis 2 : travelling as part groups had a role to play in the individuals who survived on the titanic?
