Titanic Passenger Survival Analysis

Type of tree: Classification
Task: Classify which passengers survived the sinking of The Titanic
Story behind the data: The sinking of the Titanic is a famous event, and new books are still being published about it. Many well-known facts - from the proportions of first-class passengers to the "women and children first" policy, and the fact that that policy was not entirely successful in saving the women and children in the third class - are reflected in the survival rates for various classes of passenger. These data were originally collected by the British Board of Trade in their investigation of the sinking.
For each person on board the fatal maiden voyage of the ocean liner Titanic, this dataset records sex, age (adult/child), booking class (first/second/third class, or crew) and whether or not that person survived. Note: There is not complete agreement among primary sources as to the exact numbers on board, rescued, or lost.
