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

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

The 11 MS Excel Chart Types

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.

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 showthe relationship of individual items to the whole.

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.

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.

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 a significant element

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.

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 nestedPie-Charts

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.

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 patternsindicate areas thatare in the samerange of values.

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

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.

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:

)y()yn()x()xn(

)y)(x()yxn(R

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.

Goodness of FitR Value Correlation

0.9 to 1.0 Very high positive

0.7 to 0.9 High positive

0.5 to 0.7 Moderate positive

0.3 to 0.5 Low positive

-0.3 to 0.3 Little, if any

-0.5 to -0.3 Low negative

-0.7 to -0.5 Moderate negative
