## 统计代写|金融统计代写Financial Statistics代考|Data Presentation: Tables

All data tables have four elements: a caption, column labels, row labels, and cells. The caption describes the information that is contained in the table. The column labels identify the information in the columns, such as the gross national product, the inflation rate, or the Dow Jones Industrial Average. Examples of row labels include years, dates, and states. A cell is defined by the intersection of a specific row and a specific column.

Example 2.2 Annual CPI, T-Bill Rate, and Prime Rate. To illustrate, Table $2.1$ gives some macroeconomic information from 1950 to 2010 . The caption is “CPI, T-bill rate, and prime rate (1950-2010).” The row labels are the years 1950-2010. The column labels are CPI (consumer pace index), 3-month T-bill rate, and prime rate. Changes in the consumer price index, the most commonly used indicator of the economy’s price level, are a measure of inflation or deflation. (For a more detailed description of the CPI, see Chap. 19.) The 3-month T-bill interest rate is the interest rate that the USA Treasury pays on 91-day debt instruments, and the prime rate is the interest rate that banks charge on loans to their best customers, usually large firms. This table, then, presents macroeconomic information for any year indicated. For example, the CPI for 2010 was $218.1$ and the prime rate in 2008 was $5.09 \%$. The relationship between the CPI and 3-month T-bill rate will be discussed in Chap. $19 .$

## 统计代写|金融统计代写Financial Statistics代考|Data Presentation: Charts and Graphs

It is sometimes said that a picture is worth a thousand words, and nowhere is this statement more true than in the analysis of data. Tables are usually filled with highly specific data that take time to digest. Graphs and charts, though they are often less detailed than tables, have the advantage of presenting data in a more accessible and memorable form. In most graphs and charts, the independent variable is plotted on the horizontal axis (the $x$-axis) and the dependent variable on the vertical axis (the $y$-axis). Frequently, “time” is plotted along the $x$-axis. Such a graph is known as a time-series graph because on it, changes in a dependent variable (such as GDP, inflation rate, or stock prices) can be traced over time.

Line charts are constructed by graphing data points and drawing lines to connect the points. Figure $2.1$ shows how the rate of return on the S\&P 500 and the 3-month T-bill rate have varied over time. ${ }^1$ The independent variable is the year (ranging from 1990 to 2010), so this is a time-series graph. The dependent variables are often in percentages.

Figure $2.2$ is a graph of the components of the gross domestic product (GDP)personal consumption, government expenditures, private investment, and net exports-over time. This is also a time-series graph because the independent variable is time. It is a component-parts line chart. These series have been “deflated” by expressing dollar amounts in constant 2005 dollars. (Chap. 19 discusses the deflated series in further detail.)

Figure $2.2$ is also called a component-parts line graph because the four parts of the GDP are graphed. The sum of the four components equals the GDP. Using this type of graph makes it possible to show the sources of increases or declines in the GDP. (The data used to generate Fig. $2.2$ are found in Table 2.2.)

Bar charts can be used to summarize small amounts of information. Figure $2.3$ shows the average annual returns for Tri-Continental Corporation for investment periods of seven different durations ending on September 30, 1991. This figure shows that Tri-Continental has provided investors double-digit returns during a 50-year period.

It also shows that the investment performance of this company was better than that of the Dow Jones Industrial Average (DJIA) and the S\&P $500 .^2$
