- Spreadsheets below will allow students to practice MS Excel features during class and at home.
__________________________________________________ Formulas and Functions / Working with Data**Conditional Formatting**(CF) is a tool that allows you to apply formats to a cell or range of cells, and have that**formatting**change depending on the value of the cell or the value of a formula. For example, you can have a cell appear bold only when the value of the cell is greater than 100.**Logical functions (reference)**
Function DescriptionAND function Returns TRUE if all of its arguments are TRUE FALSE function Returns the logical value FALSE IF function Specifies a logical test to perform IFERROR function Returns a value you specify if a formula evaluates to an error; otherwise, returns the result of the formula ________________________________________________________________ Data AnalysisLoad and activate the Analysis ToolPak. Click the File tab, click Options, and then click the Add-Ins category. In the Manage box, select Excel Add-ins and then click Go. In the Add-Ins box, check the Analysis ToolPak check box, and then click OK.If you need to develop complex statistical or engineering analyses, you can save steps and time by using the Analysis ToolPak. You provide the data and parameters for each analysis, and the tool uses the appropriate statistical or engineering macro functions to calculate and display the results in an output table. Some tools generate charts in addition to output tables. The data analysis functions can be used on only one worksheet at a time. When you perform data analysis on grouped worksheets, results will appear on the first worksheet and empty formatted tables will appear on the remaining worksheets. To perform data analysis on the remainder of the worksheets, recalculate the analysis tool for each worksheet. The Analysis ToolPak includes the tools described in the following sections. To access these tools, click Data Analysis in the Analysis group on the Data tab. If the Data Analysis command is not available, you need to load the Analysis ToolPak add-in program.- Histogram - non numeric

- The first argument
**sets up the condition**the IF function will test: In this example, if the value in cell D6 is greater than or equal to 100. So our first argument will be**D6>=100**. - The second argument tells the function
**what to write**if the condition is**true**. In this example, if the value is greater than or equal to 100, we want it to write "0" in the cell. So our second argument will be**0**. - The third argument tells the function
**what to write**if the condition is**false**: In this example, if the value is less than 100, we want it to use the value from cell G3 (5.99). So our third argument will be**$G$3**(we'll use an absolute reference here just in case we move this formula in the future).

Calculations**Calculation**is the process of computing formulas and then displaying the results as values in the cells that contain the formulas. To avoid unnecessary calculations, Microsoft Excel automatically recalculates formulas only when the cells that the formula depends on have changed. This is the default behavior when you first open a workbook and when you are editing a workbook. However, you can control when and how Excel recalculates formulas.**Iteration**is the repeated recalculation of a worksheet until a specific numeric condition is met. Excel cannot automatically calculate a formula that refers to the cell — either directly or indirectly — that contains the formula. This is called a circular reference. If a formula refers back to one of its own cells, you must determine how many times the formula should recalculate. Circular references can iterate indefinitely. However, you can control the maximum number of iterations and the amount of acceptable change.**Precision**is a measure of the degree of accuracy for a calculation. Excel stores and calculates with 15 significant digits of precision. However, you can change the precision of calculations so that Excel uses the displayed value instead of the stored value when it recalculates formulas.
