Term | Definition |
---|---|
Operator Precedence | Within parentheses first: left to right with * and / before + and - |
Strategy for developing a long formula | Create a piece at a time, verifying results of each piece before proceeding |
Function SMALL (range, k) Function LARGE (range, k) | Smallest value in a range: SMALL (range, 1) |
Function COUNT (range) | Count nonblank entries in a range |
Replace blank cells with a value and color fill | [Find&Select] -> [GoToSpecial] -> [Blanks] -> select color -> enter value -> [Ctrl][Enter] |
Insert column to left | Highlight column, right-click -> [Insert] |
Rearrange columns | Click column header of column to move. In Home tab, [Clipboard], right-click column header of column to move to, right-click the column header of column to move -> Cut. Click column header to right of where column is to go. Right-click and select [Insert |
Rescale values, e.g., from 5 to 10 or from 15 to 10 | Multiply original by the multiplier (whole number or fraction), e.g., for 5 to 10, multiply by 2, for 15 to 10, multiply by 2/3 |
Average a range omitting smallest value | =(SUM(range)-SMALL(range,1))/ (COUNT(range)-1) |
Absolute and relative references | Relative reference: A8 Absolute column only: $A8 Absolute row only: A$ Absolute column & row: $A$8 Press [F4] to cycle choices |
Copy/propagate formula to bottom of range | Highlight formula cell(s) and move cursor to lower right corner. When cursor changes to a bold +, double-left click. |
Shortcut: Display format Cells | [Ctrl]1 |
Hardcoding (sure way to make errors!) | Typing values rather than using references to cells containing parameters |
Parameters | Values that can vary over time, i.e., interest rates, weights. Using formula references to these values is parameterization. |
Built-in functions | Examples: average, minimum, maximum, count, small, IF |
Excel: IF function Access: IIF function | IF(logicalTest, [valueIfTrue], [valueIfFalse]) When logicalTest returns a value of TRUE, [valueIfTrue] goes in the cell. When logicalTest returns a value of FALSE, [valueIfFalse] goes in the cell. |
Nested IFs and IIFs | In an IF/IIF function, [valueIfTrue] and [valueIfFalse] arguments can be IF/IIF functions (64 nested levels for Excel; unlimited for Access) |
VLOOKUP Function | VLOOKUP(lookupValue, tableArray, ColIndexNum, rangeLookup) rangeLookup = FALSE for exact match rangeLookup = TRUE or omitted for approximate match |
VLOOKUP table format for [tableArray] argument | First column: Values sorted ascending for looking up Columns after first: Values to extract |
Change column width | Place and hold cursor on right border of column header and drag border to desired column width. |
Blanks ignored in calculations | Excel ignores blank cells, in calculations and in formulas unless a function specifically treats them otherwise. Variants of the COUNT* function will identify blank cells. |
Macro | Saved sequence of keystrokes for later execution to enable users to reduce time to perform repetitive tasks. |
Create macro | 1. Practice keystrokes 2. Enable Developer tab: FILE tab -> Customize Ribbon, check DEVELOPER 3. In DEVELOPER tab -> Record Macro 4. Name macro (no spaces 5. Enter shortcut key -> OK 6. Enter keystrokes for macro 7. In DEVELOPER tab -> Stop Recordin |
Execute macro | [CTRL] [SHIFT] letter |
Sort data | 1. Highlight data range with headers 2. DATA tab -> Sort -> check “My data has headers” 3. Set Column pulldown menu to first sort field 4. For within level sorting, -> Add Level and select field 5. Reset sort order if needed |
VLOOKUP Function | VLOOKUP(lookupValue, tableArray, ColIndexNum, rangeLookup) rangeLookup = FALSE for exact match rangeLookup = TRUE or omitted for approximate match |
Create pivot table | 1. Highlight data range including headings 2. INSERT tab -> PivotTable -> OK 3. In PivotTable Fields, select field Row Labels 4. Drag fields to ∑ Values 5. For each ∑ Values field, pull down menu; select Value Field Setting 6. Format colum |
Function CONCATENATE | Put cell contents together: CONCATENATE (comma-separated arguments) |
Circular reference | A cell referencing itself directly or indirectly through a sequence of formulas, creating a logic error |
