泰坦尼克号获救率数据分析报告，用数据揭露真相。
一，船上乘客生存率分析报告
泰坦尼克号生存率仅有38%的，可见此次事件救援不力，救生艇严重不足，且泰坦尼克号号撞得是冰山，海水冷，没有救生艇，在水里冻死的乘客不少。
二，哪个年龄段存活率最高（青年人（18岁以下），中年人（18到50岁），老年人（50岁以上））
数据分析：看图我们得到，年轻人获救率最高50%，老年人获救率最低0.39，中年人死亡人数最多。发生生命危险时，自救能力最强的中年人还是起到了中流砥柱的作用。不要再叫猥琐油腻中年男了哦，他们才是社会的扛把子。
3,女性乘客和男性乘客获救率分析
从图中可以看到，女性的获救率远远高于男性，女士优先不是一句空话。
4，船上一等舱二等舱三等舱的乘客贫富差距情况
从图中可以看出，一等舱占全船24%的人数，消费额时全船的67%的金额。嗯，符合著名的二八法则，80%的财富掌握在20%的人手里。
5，舱位和获救率关系分析
从图中可以看出，一等舱的获救率时三等舱的三倍左右，说明发生沉船事故时，一等舱先上救生艇的，有钱能使鬼推磨，古人诚不欺我也。
