Look out for these terms as you read.You will define them later.What is a Spreadsheet?A spreadsheet is data displayed in rows and columns.The spreadsheet application in Microsoft Office is Excel.Excel files are called workbooks, each workbook contains three worksheets. The default file name for an Excel workbook is Book1.When saved, Excel files have an extension of .xlsxBasic PartsThe cell is the intersection of a row and column where data is stored.Columns are named by Letter (A, B, C, D)Rows are named by Number (1, 2, 3, 4)A cell reference (or the name of a cell) is the column letter and row number where that cell is located.

Cell ReferenceColumn LetterRow Number

The Name Box displays the cell reference of the active cell.

The formula bar displays the contents of the active cell.Entering DataData can only be entered into the active cell. The active cell has a darker border than the other cells. Data will be displayed on screen in the active cell and in the formula bar. To enter data, select the cell and begin typing.What can be entered?Labels: text that canned be used in calculations.Values: numbers that can be used in calculationsDates/times: times or dates that may be used in some calculations.Entering DataOnce data has been entered into a cell:Pressing the Enter key selects the next cell in the columnPressing an arrow key selects the next cell in the direction of the arrow key pressed.Pressing the Esc key cancels data entry and restores the original contents of the cell.Pressing the tab key when entering information is the most efficient method of entering data across a row.Excel will recognize a pattern and return to the beginning of a row when you press Enter.Use the next slide to label your Excel Window handout.The Excel Window

Formatting Numeric DataFormatting valuesCells storing numeric data (values) should be properly formatted to reflect the type of value stored.From the ribbonTab: HomeGroup: Number

Formatting ValuesClick on the category drop-down menu for your choices.

Choose the Number Group Dialog box launcherChoose your category, decimal places, etc.Common Numeric FormatsNumber formats the active cell to display values with two decimal places.Currency formats the active cell to display values with a dollar sign and two decimal places.Accounting is similar to Currency except the dollar sign aligns itself at the left edge of the cell. Percentage formats the active cell to display values as percentage with two decimal places.Scientific formats the active cell to display values in scientific notation with two decimal places.Options:There are three options associated with numeric formats:Decimal placesComma separatorNegative numbers

Formatting Numbers (Values)Formatting a cell does not change the value that is stored in the cell, only how that value is displayedNumber signs (######) are displayed if a cell is not wide enough to display the formatted number.There are also different options for Dates & Times.

Date OptionsTime OptionsUsing Formulas to Perform CalculationsFormulas in ExcelOne benefit of using a worksheet is its ability to perform calculations using formulas.Formulas are mathematical statements used to calculate values.Always begin with an equal (=) sign.Formulas in ExcelMathematic operators used in formulas:Exponentiation^Multiplication*Division/Addition+Subtraction-Excel evaluates a mathematical expression using a specific order of operations.Please Excuse My Dear Aunt SallyParenthesis, Exponents, Multiply, Divide, Add, SubtractComplete practice 4 from your packet. You will practice entering labels and formulas into Excel.Practice 4Using Cell References in FormulasUsing Cell ReferencesGenerally, cell references will be used in formulas instead of numbers. A cell reference is used in a formula so that the value stored in the cell is used in the calculation of the formula.

Excel uses the cell reference to locate the value needed for the calculation.

Using Cell ReferencesFormulas that contain cell references are automatically recalculated when the value in a references cell changes.A formulas cannot reference the cell it is stored in, this is called a circular reference.

Complete practice 5 from your packet. You will practice entering labels and formulas using cell references into Excel.Practice 5Using Functions to Perform CalculationsUsing Functions Excel contains built-in functions that can be included in a formula for performing common calculations.A function performs a calculation that results in a single value.A function has two parts, the function name, and the argument.=SUM(G1:G3)

Functions are useful because they make a formula shorter and less error-prone.functionargumentComplete practice 6 from your packet. You will practice entering labels and functions into Excel.Practice 6PointingEntering Formulas - PointingWhen typing a formula, cell references can be entered by pointing.Pointing is a technique where a formula is typed up to where a cell references should appear and then a cell is clicked, which places its reference in the formula.Pointing is the best method for entering cell references into a formula because typing errors are avoided.Additional VocabularyAdditional VocabularyAdd the following Vocabulary terms and definitions to your Excel vocabulary list:Adjacent cells cells that are next to each otherArgument data required by a function to perform calculations.Formula mathematical statement used to calculate a value.Function performs a calculation that result sin a single valuePointing clicking a cell to place its reference in a formulaRange selection of two or more cellsFormula bar area near the top of the worksheet window that displays the contents of the active cell.
