Hand-drawn diagrams represent data in a way that is difficult for computers to interpret. Data Hand Book teaches you how to make reliable hand-drawn charts and diagrams based on your own data. The book shows you how to identify data points, segment it, select the appropriate charting tool for your needs, and plan its layout—all with examples of completed charts that are broken into simple steps. The book offers guidelines for accurately capturing the total number of pixels in a bar or pie graph as well as guidelines for drawing lines that are equal distances apart, making it easier to see comparisons among categories. It also offers guidelines on designing histograms to show frequencies rather than heights or widths. There are examples of charts that provide easy-to-read information to help you understand your data set, such as bar graphs, histograms, pie charts, and line graphs. Other charts show how to plot sequential data in order to compare patterns, such as differences in the numbers of men and women who completed college. Data Hand Book teaches how to draw differently shaped curves or lines so that you can compare different sets of data. The book also examines how to plot functions (arithmetic) and compare functions (percentages) using line graphs. It gives guidelines for quickly creating regression charts for comparing two sets of data or plotting y-y scatter diagrams. Data charts help you identify patterns or trends, compare differences, or assess proportions. The book explains how to use computer software to design these charts. Hand-drawn diagrams are still the most effective way to present quantitative data in a range of disciplines including engineering, marketing, law, accounting, science, business, sociology and psychology. Data Hand Book provides information on capturing raw data digitally so that you can import it into your favorite computer spreadsheet program for advanced analysis. It also shows how you can instantly publish your charts online using PowerPoint Slides. Some charts help you to identify a pattern or trend—such as those used by engineers to plot X-Y data. Other charts compare one set of data with another—such as those used by marketers to plot survey results.

In addition, line graphs provide a different perspective on the same information that is displayed in a bar graph or histogram. The book begins with a section that describes how to capture raw data digitally and import it into your favorite spreadsheet program for advanced analysis. It also explains how PowerPoint Slides enable you to instantly publish your charts online. The book then offers guidelines that describe how to design each type of chart—including bar graphs, histograms, pie charts, line graphs, and scatter diagrams. There are also guidelines on creating slopes and plotting functions (arithmetic) and comparing functions (percentages). You will learn how to select the appropriate charting tool for your needs. You will be guided through the steps of capturing raw data digitally so that it appears on your computer screen and you can import it into a spreadsheet for advanced analysis. This is followed by a section on designing charts using PowerPoint Slides. eccc085e13
