2 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 2 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods Learning Goals  Construct Formatted Tables in Excel Use the Cell Formatting Commands  Construct Charts and Graphs Comparison Charts → Bar, Col, Radar Analysis Charts → Scatter, Surface –Curve Fits → Linear Regression  Use tables and graphs as problem solving tools

3 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 3 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods Using Tables & Charts  Engineers record and present data in two primary formats: Tables and Graphs

4 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 4 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods Tables in Reports  When using Tables in Reports and Presentations Tables should always have: –a Title –Column headings with brief descriptive names, symbols and appropriate units. Numerical data in the table should be written to the proper number of significant digits. The decimal points in a column should be aligned. Tables should always be referenced and discussed/explained in the body of the text of the document containing the table

9 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 9 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods Charts & Graphs cont  Where Appropriate Annotate or Mark points/regions of Interest with Arrows, Ovals, or Text  There are 11 different chart types in Microsoft Excel (and several variations of each type) This Covers 99.9% of the Chart Types That Most Engineers will need Consider Next the Criteria for application

10 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 10 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods The 11 MS Excel Chart Types

11 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 11 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Area Chart An area chart emphasizes the magnitude of change over time. By displaying the sum of the plotted values, an area chart also shows the relationship of parts to a whole.

12 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 12 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Bar Chart A bar chart illustrates comparisons among individual items. Categories are organized vertically, values horizontally, to focus on comparing values and to place LESS emphasis on time. Stacked bar charts show the relationship of individual items to the whole.

13 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 13 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Column Chart A column chart shows data changes over a period of time or illustrates comparisons among items. Categories are organized horizontally, values vertically, to emphasize variation over time. Stacked column charts show the relationship of individual items to the whole.

14 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 14 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Line Chart A line chart shows trends in data at equal intervals. Although line charts are similar to area charts, line charts emphasize time flow and the rate of change, rather than the amount of change or the magnitude of values.

15 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 15 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Pie Chart A pie chart shows the proportional size of items that make up a data series to the sum of the items. It always shows only one data series and is useful when you want to emphasize ONE significant element

16 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 16 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  XY (Scatter) Chart An xy (scatter) chart either shows the relationships among the numeric values in several data series or plots two groups of numbers as one series of xy coordinates. It shows uneven intervals, or clusters, of data and is commonly used for scientific data.

17 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 17 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Doughnut Chart Like a pie chart, a doughnut chart shows the relationship of parts to a whole, but it can contain more than one data series. Each ring of the doughnut chart represents a data series Basically nested Pie-Charts

18 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 18 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Radar Chart In a radar chart, each category has its own value axis radiating from the center point. Lines connect all the values in the same series. A radar chart compares the aggregate values of a number of data series.

19 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 19 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Surface Chart A 3D surface chart is useful when you want to find optimum combinations between two sets of data. As in a topographic map, colors and patterns indicate areas that are in the same range of values.

20 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 20 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Bubble Chart A bubble chart is a type of xy (scatter) chart. The size of the data marker indicates the value of a third variable.

21 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 21 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Stock Chart The stock chart is often used to illustrate stock prices. This chart can also be used for scientific data, for example, to indicate temperature changes

22 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 22 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods MS Excel Charts  Cone, Cylinder, and Pyramid Chart The cone, cylinder, and pyramid data markers can lend a dramatic effect to 3-D column and bar charts.

60 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 60 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods Coefficient of Correlation  The coefficient of correlation is an indication of how well the linear relationship determined by the method of least squares fits the data set.  The equation for the coefficient of correlation is:

61 BMayer@ChabotCollege.edu ENGR-25_Lec-29_MS_Excel-2.ppt 61 Bruce Mayer, PE Engineering/Math/Physics 25: Computational Methods Interpretation of R  If R is 0, the points are so scattered that the regression line does not help predict y for a given x.  If R is +1 (positive slope) or –1 (negative slope), the points actually lie on a straight line so almost perfect predictions of y for a given x can be made using the regression line.
