人教版高中数学选修3分类变量与列联表教学设计
一、 问题导学前面两节所讨论的变量,如人的身高、树的胸径、树的高度、短跑100m世界纪录和创纪录的时间等,都是数值变量,数值变量的取值为实数.其大小和运算都有实际含义.在现实生活中,人们经常需要回答一定范围内的两种现象或性质之间是否存在关联性或相互影响的问题.例如,就读不同学校是否对学生的成绩有影响,不同班级学生用于体育锻炼的时间是否有差别,吸烟是否会增加患肺癌的风险,等等,本节将要学习的独立性检验方法为我们提供了解决这类问题的方案。在讨论上述问题时,为了表述方便,我们经常会使用一种特殊的随机变量,以区别不同的现象或性质,这类随机变量称为分类变量.分类变量的取值可以用实数表示,例如,学生所在的班级可以用1,2,3等表示,男性、女性可以用1,0表示,等等.在很多时候,这些数值只作为编号使用,并没有通常的大小和运算意义,本节我们主要讨论取值于{0,1}的分类变量的关联性问题.
人教版高中地理选修3第一章第一节现代旅游教案
香港的旅游特色在“购”，而购物旅游又进一步促进了其他要素的发展。据统计，每年进入香港的国际旅游者中有60％左右的人是为了购物，其购物费用也占全部旅游费用支出的60％左右，使香港这个弹丸之地成为世界的“购物天堂”。思考：1．从旅游六要素的角度看，香港的“购”是如何促进旅游业发展的?点拨：到香港购物是许多游客来港旅游的主要动机。“购”是香港旅游六要素的核心，促进了整个旅游业的发展。2．香港的地理位置和自由港的地位，为旅游业的发展提供了哪些有利条件?点拨：香港是自由港，商品来自世界各地，由于大部分商品不收关税，香港的商品价格就相应较低。此外，这里每年都有许多换季大减价的促销活动，能为游客提供真正的实惠。香港店铺中销售着世界各地不同特色的货品，而且大部分服务行业的从业人员都受过专业训练，态度殷勤友善，以客为先。购物成为香港吸引游客的一个重要因素，为旅游的发展提供了极为有利的条件。
