A box and whisker plot is developed from five statistics. 1  Minimum value â the smallest value in the data set. 2  Second quartile â the value below which the lower 25% of the data are contained. 3  Median value â the middle number in a range of numbers. 4  Third quartile â the value above which the upper 25% of the data are contained.
An obvious possible reason for the Titanic sinking is the weather on the Atlantic during the time of the tragedy. The ocean was unusual because of the calm sea without wind or swell. Under normal conditions the waves would have broken over the base of the iceberg giving lookouts sooner warning.
For decades after the disaster, there was little doubt about what sank the Titanic. When the unsinkable ship, the largest, most luxurious ocean liner of its time, crashed into an iceberg on its maiden voyage in 1912, it took more than 1,500 of its 2,200 passengers to the bottom. As the ship slipped into the North Atlantic, so, too, did the secret of how and why it sank.
