由樣本相關系數(shù)??≈0.97,可以推斷脂肪含量和年齡這兩個變量正線性相關，且相關程度很強。脂肪含量與年齡變化趨勢相同.歸納總結1．線性相關系數(shù)是從數(shù)值上來判斷變量間的線性相關程度，是定量的方法．與散點圖相比較，線性相關系數(shù)要精細得多，需要注意的是線性相關系數(shù)r的絕對值小，只是說明線性相關程度低，但不一定不相關，可能是非線性相關．2．利用相關系數(shù)r來檢驗線性相關顯著性水平時，通常與0.75作比較，若|r|>0.75，則線性相關較為顯著，否則不顯著．例2. 有人收集了某城市居民年收入(所有居民在一年內(nèi)收入的總和)與A商品銷售額的10年數(shù)據(jù),如表所示.畫出散點圖，判斷成對樣本數(shù)據(jù)是否線性相關，并通過樣本相關系數(shù)推斷居民年收入與A商品銷售額的相關程度和變化趨勢的異同.

人教版高中數(shù)學選修3離散型隨機變量的均值教學設計
對于離散型隨機變量，可以由它的概率分布列確定與該隨機變量相關事件的概率。但在實際問題中，有時我們更感興趣的是隨機變量的某些數(shù)字特征。例如，要了解某班同學在一次數(shù)學測驗中的總體水平，很重要的是看平均分；要了解某班同學數(shù)學成績是否“兩極分化”則需要考察這個班數(shù)學成績的方差。我們還常常希望直接通過數(shù)字來反映隨機變量的某個方面的特征，最常用的有期望與方差.二、 探究新知探究1.甲乙兩名射箭運動員射中目標靶的環(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n足夠大時，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,這個平均值的大小可以反映甲運動員的射箭水平.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.

溫故知新 1.離散型隨機變量的定義可能取值為有限個或可以一一列舉的隨機變量,我們稱為離散型隨機變量.通常用大寫英文字母表示隨機變量,例如X,Y,Z;用小寫英文字母表示隨機變量的取值,例如x,y,z.隨機變量的特點: 試驗之前可以判斷其可能出現(xiàn)的所有值，在試驗之前不可能確定取何值；可以用數(shù)字表示2、隨機變量的分類①離散型隨機變量:X的取值可一、一列出；②連續(xù)型隨機變量:X可以取某個區(qū)間內(nèi)的一切值隨機變量將隨機事件的結果數(shù)量化．3、古典概型:①試驗中所有可能出現(xiàn)的基本事件只有有限個；②每個基本事件出現(xiàn)的可能性相等。二、探究新知探究1.拋擲一枚骰子,所得的點數(shù)X有哪些值？取每個值的概率是多少？ 因為X取值范圍是{1，2，3，4，5，6}而且"P(X=m)"=1/6,m=1,2,3,4,5,6.因此X分布列如下表所示

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Reading and Thinking教學設計
The topic of this part is “Discover the reasons for festivals and celebrations.The Listening & Speaking & Talking part aims at talking about the experiences and feelings or emotions about the festivals and celebrations. This section aims at detecting the reason why the people celebrate the festivals, the time, the places, the types and the way of celebrations. It also explains why some traditions in the old celebrations are disappearing, like the firecrackers in the big cities and some new things are appearing like the prosperity of business or commerce. 1. Students can talk about what festivals they know and the reasons and the way of celebrating them.2. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.3. Students can understand the past, the present situation of some festival around the world and why there are some changes about them. 4. Students can have the international awareness about the festivals.1. Students should learn the reading skills such as the headline and get the topic sentences, the structures of articles.2. Students can understand the past, the present situation of some festival around the world and why there are some changes about them.Step 1 Lead in---Small talkWhat festival do you like best ? Why ?I like the Spring Festivals because I can set off the fireworks, receive the lucky money and enjoy the Gala with my families.Step 2 Before reading---Pair workWhy do people celebrate different festivals ?The Spring Festivals is to celebrate the end of winter and the coming of spring and new life.The Mid-autumn Day is to celebrate the harvest and admire the moon.
新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學設計
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

The topic of this part is “Learn to make choices in life”.The Listening & Speaking & Talking part aims at the moral dilemmas, and this part is about making choices in life. The heroin is Lin Qiaozhi, a famous medical scientist, made a great contribution to our country’s medical care. Most importantly, her life experience can inspire our students whether in studying or the development of career. she had moral dilemmas and life choices, which are similar to the students who will step into society. Besides, Lin has quite good virtues like kindness, self-improvement, insistence, job-loving , generosity and responsibility, which is worth being learned.Concretely, this article is a biography about Lin Qiaozhi. The article tells her whole life according the timeline, among which the life choices is emphasized. For example, whether married or chased her dream, returned home or stayed abroad, family or public, her choices all reflected her faith, spirit, responsibility and devotion.1.
