EXCEL Study Guide #2

Spreadsheet Terms  Input Collection of information – the data to be typed into the spreadsheet.  Output Worksheet results.

Three types of information that can be typed in a cell  Labels  Labels (Text)  Values  Values (Numbers)  Formulas  Formulas (Calculations)  =B5+B6+B7  Include  Include Functions

LABELS  Labels are text entries – Labels identify the data in rows and columns.  Left Aligned in cell.  Excel recognizes a # as a label if an apostrophe precedes the number.  Ex: ‘

Values  Values are the numbers that are used in calculations.  A value is an entry that begins with a number or certain symbols. For example a + -. $ sign  If the value is to large for the cell, the number disappears and the #### symbol or scientific notation appears in the cell.  Values are right Aligned in the Cell

Formulas  Formulas — Perform calculations  Adding, multiplying averaging, etc.  Formula prefix (= ).  Ex: =f4+g4+h4+i4

Operators  Arithmetic operators  Must be used in formulas  The following operators are used in Excel formulas: + for addition) - for subtraction * for multiplication / for division

Order of Preference Order operations are performed in formula  Operations in parentheses Jump to front of line — calculated 1 st If NO parenthesis then the order is as follows:  Calculated 1st — Exponents  2nd — Multiplication & division, left to right  3rd — Addition & subtraction, left to right

FUNCTIONS  A function is a predefined or built-in worksheet formula  Functions & formulas begin with = sign  Type in functions manually OR  Use the Paste Function feature which is the fx tool on the toolbar  The following is an example of a function =AVERAGE(B13:C26)

Common Functions SUM — Calculates the sum of the arguments AVERAGE — Calculates the average of the arguments MAX — Displays largest value MIN — Displays smallest value COUNT — Calculates number of values

Arguments Values (numbers used to calculate in the formula)Values (numbers used to calculate in the formula) Excel has the capability to calculate Values, Text, a range of cells, or another functionExcel has the capability to calculate Values, Text, a range of cells, or another function

Autosum  The Autosum Tool is a built-in SUM function  The Autosum button is on the toolbar for easy, quick access because summing is done so frequently.

Autosum Continued The autosum feature is programmed to add the values above the cell pointer first. If Excel finds no values above the cell pointer, then it adds values in the cells to the left of the cell pointer.

Cell Reference Using cell addresses or range of cells in a formula is called cell referencing. Example: =B5+B6+B7+B8 instead of =

Cell Reference It is usually more effective to use a cell reference than values in a formula or function. If the values are edited or changed, then the formula automatically recalculates.

Cell Range  The definition of a Range is A group of cells (two or more)  A range of cells can be named  Range names can be used in formulas and to move around the workbook
