人教版高中數(shù)學(xué)選修3離散型隨機(jī)變量的均值教學(xué)設(shè)計(jì)
對于離散型隨機(jī)變量，可以由它的概率分布列確定與該隨機(jī)變量相關(guān)事件的概率。但在實(shí)際問題中，有時(shí)我們更感興趣的是隨機(jī)變量的某些數(shù)字特征。例如，要了解某班同學(xué)在一次數(shù)學(xué)測驗(yàn)中的總體水平，很重要的是看平均分；要了解某班同學(xué)數(shù)學(xué)成績是否“兩極分化”則需要考察這個(gè)班數(shù)學(xué)成績的方差。我們還常常希望直接通過數(shù)字來反映隨機(jī)變量的某個(gè)方面的特征，最常用的有期望與方差.二、 探究新知探究1.甲乙兩名射箭運(yùn)動(dòng)員射中目標(biāo)靶的環(huán)數(shù)的分布列如下表所示：如何比較他們射箭水平的高低呢？環(huán)數(shù)X 7 8 9 10甲射中的概率 0.1 0.2 0.3 0.4乙射中的概率 0.15 0.25 0.4 0.2類似兩組數(shù)據(jù)的比較,首先比較擊中的平均環(huán)數(shù),如果平均環(huán)數(shù)相等，再看穩(wěn)定性.假設(shè)甲射箭n次，射中7環(huán)、8環(huán)、9環(huán)和10環(huán)的頻率分別為：甲n次射箭射中的平均環(huán)數(shù)當(dāng)n足夠大時(shí)，頻率穩(wěn)定于概率，所以x穩(wěn)定于7×0.1+8×0.2+9×0.3+10×0.4=9.即甲射中平均環(huán)數(shù)的穩(wěn)定值(理論平均值)為9,這個(gè)平均值的大小可以反映甲運(yùn)動(dòng)員的射箭水平.同理，乙射中環(huán)數(shù)的平均值為7×0.15+8×0.25+9×0.4+10×0.2=8.65.

一、 問題導(dǎo)學(xué)前面兩節(jié)所討論的變量,如人的身高、樹的胸徑、樹的高度、短跑100m世界紀(jì)錄和創(chuàng)紀(jì)錄的時(shí)間等,都是數(shù)值變量,數(shù)值變量的取值為實(shí)數(shù).其大小和運(yùn)算都有實(shí)際含義.在現(xiàn)實(shí)生活中,人們經(jīng)常需要回答一定范圍內(nèi)的兩種現(xiàn)象或性質(zhì)之間是否存在關(guān)聯(lián)性或相互影響的問題.例如,就讀不同學(xué)校是否對學(xué)生的成績有影響,不同班級學(xué)生用于體育鍛煉的時(shí)間是否有差別,吸煙是否會(huì)增加患肺癌的風(fēng)險(xiǎn),等等,本節(jié)將要學(xué)習(xí)的獨(dú)立性檢驗(yàn)方法為我們提供了解決這類問題的方案。在討論上述問題時(shí),為了表述方便,我們經(jīng)常會(huì)使用一種特殊的隨機(jī)變量,以區(qū)別不同的現(xiàn)象或性質(zhì),這類隨機(jī)變量稱為分類變量.分類變量的取值可以用實(shí)數(shù)表示,例如,學(xué)生所在的班級可以用1,2,3等表示,男性、女性可以用1,0表示,等等.在很多時(shí)候,這些數(shù)值只作為編號(hào)使用,并沒有通常的大小和運(yùn)算意義,本節(jié)我們主要討論取值于{0,1}的分類變量的關(guān)聯(lián)性問題.

新人教版高中英語必修2Unit 2 Wildlife Protection-Reading and Thinking教案二
The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.
