Presentation Transcript

  1. Spreadsheet concepts • not a word processor, not just a single text-based workspace • workspace composed of rows and columns • Cell = intersection of a row and column • Cell can contain: • Constants ( values do not change unless you edit them) • Text (labels) • Number (numeric values) • Date/time • Formulas (values change if you change the contents of reference) • calculated result based on reference to one or more cells

  2. Concepts (con’t) • Excel worksheet: single page workspace • rows 1 thru 65,536 (216 = 17 bits) [9 bit x 17 bit addr] • columns A thru Z, AA..AZ, thru IA..IV (256=28) • Excel workbook: • file containing one or more worksheets • References: (used in formulas) • Relative address (A1, J23) adjusts to changes • Absolute reference ($A$1, $J23) is static addr

  3. Terms to know: • worksheet vs workbook • Excel’s workspace (window) includes: -title bar -menu bar -toolbar(s): standard, formatting, chart, etc… -name box -formula bar -worksheet window: -frame, cells, tabs, scroll bars -status bar

  4. Terms, etc… (cont): • cell • cell address = • column letter, row number • current (or active) cell • sheet tab • navigation: • Ctrl + Home = makes A1 the current cell • End,  = lower right corner of worksheet (IV65536) • End,  = last row in worksheet (row 65536) • F5 (GoTo) = type in cell address • Esc = to quit current operation without changing values

  5. Concepts to know… • Entering/ displaying/ modifying data – • display cell vs. formula bar value • columns or rows (height, width, auto-fit, hide, unhide) • adding/deleting rows/columns/worksheets • selecting rows/columns/cells • select or drag with mouse • shift+ for range vs. ctrl+ for non-contiguous cells • notice status bar and name box during selection process • shortcut keys: ctrl + [cut=x / copy=c / paste=v] • AutoFill – use fill handle to complete a series • tools\options…\custom lists – to add new lists

  6. Concepts (con’t)… • Format data – (by cell, row, column, selection) • “Format\Cells…” • Number – • general, currency/accounting, date/time, text, custom… • decimal places, profit (loss), color, special formats • Alignment – align, wrap, merge, shrink • Font – (same as other GUI apps) • Border – apply styles by cell or selection • Patterns – cell color, shading, patterns • Protection – lock or hide selection (must protect sheet to implement) • labels (text) • wrap text to fit in narrow column • merge adjacent cells to span several columns

  7. Concepts (con’t)… • Format groups of cells…to enhance the look • Add borders to enhance data areas • Add color, bold, italics, etc… • Add useful titles • Use font variations • Text: • merge cells to group columns with a heading • Numbers: • align numbers to right • use special number formats • apply different format to subtotals/totals • Insert page breaks

  8. Concepts (con’t)… • Format the worksheet/workbook… • “File\PageSetup…” -- (same as Setup… in print preview) • Page – allows print size adjustment of document by % • Margins – set to actual value or drag to adjust on print preview • Header/Footer – use automatic functions or customize • Sheet – • set print area • set row and column headers to repeat on secondary pages • turn on gridlines, etc… • direction of overflow pages • “File\Print Preview” • Zoom • Setup… • Page break preview

  9. Formula Concepts -- • Formula… =function(cells or cell range) • all formulas begin with “=“ equal sign • built-in “functions” (predefined formulas in excel) • financial, statistical, date/time, text, etc… • contain relative and or absolute references to cells • (F4 to switch through relative/absolute references) • four types or operators: • Arithmetic ( ) ^ * / + - order of precedence • Reference – indicates a selection or range of cells… (comma, colon) • =SUM(B4:F4) =SUM(B4,M6) • Comparison – tests relationship between two items… = < > • IF (C3<D6, “Yes”, “No”) • Concatenation – joins text entries into one… & (ampersand) • =C4&C3

  10. Formula Concepts (con’t) -- • 3 ways to enter formulas – • Type an equation into a cell • when equations are simple • Type-and-point in cell • when cells are easily visible • Formula wizard • when formula is complex or unfamiliar • Copy formulas with Ctrl+c ; paste with Ctrl+v • Or use fill tool (AutoFill) to replicate across cells • Displaying formulas instead of results – • “tools\options\view”…. check windows-options\formulas

  11. ** Homework assignment ** due June 30th to review in class • Read your e-mail on osprey • Excel2000 Essentials, • Project 5, Challenge Exercise (page 132-134) Challenge exercise # 1-4 • Project 6, Challenge Exercise (page 161-162) Challenge exercise # 1-4 • The files you need are • XL1-0505.xls and XL1-0603.xls
