  1. Microsoft excel 2003 Dr. Yan Liu Department of Biomedical, Industrial and Human Factors Engineering Wright State University

  2. Window Default name Title bar

  3. Window • Menu bar provides the user one way to access Excel commands (i.e. actions performed on worksheet) Menu bar

  4. Window Standard Toolbar • Toolbars provide quick and intuitive methods to access Excel commands without opening menus • Tools are depicted by icons Formatting Toolbar

  5. Window Formula bar Name box Formula box Active cell • Formula box displays contents typed in the active cell (cell with a heavy border) • Name box shows the cell reference of the active cell

  6. Window Question box • Question box is a handy way of starting Help Task pane • Task pane shows the tools that are likely to be used in the current task

  7. Window Columns Rows Cell A1 Workspace Worksheets

  8. Basic Operations • Concepts • Cell reference • Used to refer a specific cell • A combination of column name and row number • Range • A rectangular group of one or more cells • Denoted by the cell references of the top left cell and the bottom right cell separated by a colon • e.g. A1:B2 refers to the cells A1, A2, B1 and B2 • Selection • A cell is selected by clicking it • A range is selected by first clicking one of the four cells at its corner and then holding the mouse button and dragging the cursor over the range • Formatting • Change the manner in which a cell entry is displayed • Change the alignment, font, the number of decimals, show the value in number, percentage, fraction, currency, text, scientific notation, etc.

  9. Basic Operations • Entering Formulas • A formula is a mathematical expression that tells Excel to perform an operation • Begins with the equal symbol (=) • Arithmetic operators (in the order of precedence) • Negation (-) • Exponentiation (^) • Multiplication and division (*, /) • Addition and subtraction (+, -) • The precedence order may be overridden by using parentheses

  10. Suppose we have a laboratory heating apparatus with a thermometer calibrated in degrees of Fahrenheit. We need a table to give approximate Celsius values, shown as follows. It is known that Celsius = 5/9*(Fahrenheit – 32).

  11. Equal sign Arguments = ROUND (A10, 2) Function name Using Functions • Functions • Functions are predefined formulas that perform calculations by using specific values, called arguments, in a particular order, or structure • Begins with an equal sign (=) • Followed by the function name • Finally arguments for the function separated by commas, enclosed in a pair of parentheses

  12. Zero argument: = PI () One argument: = SQRT (A2) Two arguments: = ROUND (A2,2) Variable arguments: = SUM (A1:A10) or = SUM(A1:A10,B3,B4) Nesting function: = SQRT(SUM (A1:A10)) Using Functions • Types of Functions • Ten categories • Mathematical & trigonometric, engineering, logical, statistical, date and time, database, financial, information, lookup and reference, and text • Arguments • The number of arguments in a function may be fixed, variable or even zero • The argument can also be a function itself (nesting function)

  13. Charts • Types of Charts • Twelve standard types • Column, bar, line, pie, XY scatterplot, area, doughnut, radar, surface, bubble, stock, cylinder, cone, and pyramid • Custom types • Twenty build-in types • User-defined • XY Scatterplot • Compares two variables at once (one on the horizontal X axis and the other on the vertical Y axis) • Useful in observing the relationship between two variables • Line Chart • Distributes the order of data evenly along the horizontal axis and numerical values of data evenly along the vertical axis  • Useful in displaying trends over time

  14. Chart title Y-axis Chart area Y-axis title Plot area Data series Marker Legend Gridline X-axis X-axis title Anatomy of Chart

  15. Statistical Analysis • Statistical Functions • Over 80 most commonly used statistical computations • Data Analysis Tools • Tools >> Data Analysis • Descriptive Statistics • A quick method: Tools >> Data Analysis >> Descriptive Statistics

  16. Statistical Analysis • Descriptive Statistics (Cont.) • Use statistical functions

  17. In-Class Exercise Go to course website http://www.engineering.wright.edu/~yan.liu/ISE210/ to download In-Class Exercise One. There are three problems in this exercise in three worksheets titled “Function”, “Chart” and “Descriptive Statistics”.
