## 统计代写|Generalized linear model代考广义线性模型代写|Comprehension

1. Why do researchers in the social sciences rarely have data from the entire population of subjects that they are interested in?
2. Why is it important to have the ability to independently evaluate researchers’ interpretation of their data?
3. What trait do theoretical models, statistical models, and visual models all have in common?
4. Most undergraduate students in the social sciences will not become professional researchers in their careers. So why is it necessary that they take a statistics course?
5. What is a model? How does the scientific usage of the word “model” differ from the everyday definition of a model? How is it similar?
6. Explain:
a. Why every model is wrong in some way.
b. Why practitioners and researchers in the social sciences should use models if they are all wrong.
c. How researchers and practitioners judge whether they should use a particular model.
7. What are the four main ways that social science practitioners use statistics in their work?

1. Carl believes in the power of magnets in relieving physical pain, and he wears magnets on his body for this purpose. However, his magnetic bracelet doesn’t help with his arthritis pain. He consulted a website about healing magnets, and found that he needs to periodically change the location of the magnet on his body until his pain is relieved. Why is Carl’s hypothesis about the healing properties of magnets unscientific?
2. What would be an example of a theory in your major? Can you give an example of how that theory has given rise to a theoretical model? What would be a possible situation that would disprove the theory?
3. A researcher wishes to study stress, and so she records the heart rate of each of her subjects as they are exposed to a distressful situation. Is “heart rate” an independent or dependent variable? Justify your response.
4. A social worker wants to study the impact of the instability of a child’s home life on the child’s academic performance. She defines “instability” as the number of homes that the child lives in during a year and “academic performance” as the child’s grades that the teacher assigns on a scale from 0 to 100 . Which step of the quantitative research process is this?
5. Teresa wants to know if people who post more messages about themselves on social media are more selfish than people who do not.

a. She decides to count the number of Facebook status updates that her subjects post in a week that include the word “I.” She also administers a psychological test that her professor told her measures selfishness. By using these methods of measuring her variables, what step of the research is she engaging in?
b. Teresa believes that selfishness also causes people to post more self-centered messages on social media. Which variable is the independent variable in her study? Which variable is the dependent variable? Why?
c. Is this a correlational design or an experimental design?

1. Some cultural anthropologists study “rites of passage,” which are certain rituals where people transition from one stage of their life to another. The idea of “rites of passage” is very broad and can be applied to rituals in many cultures and in all stages of life from birth to death. An anthropologist decides to use the rite of passage framework to understand how adolescents in a specific tribal culture become recognized as adults.
a. In this context, is the idea of “rites of passage” a theory, a theoretical model, a statistical model, or a visual model?
b. When the anthropologist applies this idea to a specific culture and explains the stages of that culture’s rites of passage, is this a theory, a theoretical model, a statistical model, or a visual model?
2. A political science student is interested in the votes that legislators in different countries cast when considering different bills. The student decides that it is impractical to study every vote by every politician in every country. So, he decides to study only a selection of votes.
a. What is the population in this example?
b. What is the sample in this example?
3. A family science professor wants to study the impact of frequent quizzes on her students’ study habits. In one of her classes she does not offer quizzes. In another class, she offers a quiz once per week. In her last class she offers a quiz in every class session. In each class she asks her students how many hours per week they studied.
a. What is the independent variable in this example?
b. What is the dependent variable in this example?
c. How did the professor operationalize “study habits”?
d. Is this an experimental design or a correlation design?

## 统计代写|Generalized linear model代考广义线性模型代写|Excel

After opening Excel, you should see a screen similar to the one below, which shows a blank grid. Each of the boxes in the grid is called a cell. Selecting a cell permits you to enter a datum into it. In Excel it doesn’t matter whether each row represents a variable or whether each column represents a variable, though many users find it easier to treat columns as variables. (This also makes it easier to import a file from Excel into another data analysis program, like SPSS.) Most people use the first row or column to label their variables so that they can easily remember what the data mean.

There are a few features that you can see in Figure 1.3. First, the bottom left has three tabs labeled “Sheet1,” “Sheet2,” and “Sheet3.” A sheet is the grid that you see taking up the majority of the screen. Each Excel file can store multiple sheets, which is convenient for storing multiple datasets in the same file. The top bar displays several tools useful for formatting, permitting the user to make cosmetic changes to the data, such as select a font, color-code cells, and select the number of decimal places in a cell. If your instructor or an employer requires you to use software for data analysis, I suggest that you invest some time into exploring these and other features in the program.

The opening screen for SPSS looks similar to Excel’s opening screen, as is apparent when comparing Figures $1.3$ and 1.4. Both programs feature a grid made of cells that permit users to enter data directly into the program. In SPSS this is called the “data view.” In the data window the columns are variables and the rows are called “cases” (which are usually individual sample members, though not always).

On the bottom left of the screen in SPSS are two tabs. One highlighted in Figure $1.4$ is the data view; the other is the variable view. Clicking “Variable View” will change the screen to resemble Figure 1.5. Variable view allows users to enter information about variables, including the name, the type of variable, the number of decimal places, and more. We will discuss variable view more in Chapter 2. Until then, I recommend that you experiment with entering data into SPSS and naming variables.

SPSS 的打开屏幕看起来类似于 Excel 的打开屏幕，这在比较图时很明显1.3和 1.4。这两个程序都有一个由单元格组成的网格，允许用户将数据直接输入程序。在 SPSS 中，这称为“数据视图”。在数据窗口中，列是变量，行称为“案例”（通常是单个样本成员，但并非总是如此）。

SPSS 屏幕的左下角有两个选项卡。图中突出显示的一个1.4是数据视图；另一个是变量视图。单击“Variable View”将改变屏幕，类似于图 1.5。变量视图允许用户输入有关变量的信息，包括名称、变量类型、小数位数等。我们将在第 2 章中详细讨论变量视图。在此之前，我建议您尝试将数据输入 SPSS 并命名变量。
