CREATING FORMULAS & CHARTING DATA - MANJU

FORMULA = Equation. Used to calculate values.  FORMULA starts with = sign  FORMULA uses OPERATORS. Example +, -, /, *, %  FORMULA uses OPERANDS.  OPERANDS are Numbers and cell reference. Example 1, 100, 56, A1, B4, G6 Examples for FORMULAS  = 4+4 (using numbers)  =A1+B1 (using cell reference)  =4+A1 (using number & cell reference)  =12/2  =A1/B1

COMPLEX FORMULAS – has more than one OPERATOR  =5*4+6  =A1*B1+C1 ORDER OF EVALUATION Multiplication & Division before Addition & Subtraction  =12/6*2  =A1/B1*C1 ORDER OF EVALUATION Left to right  Wrong Formula – Wrong Result - GIGO – “Garbage In, Garbage Out”  Real time workout of Examples for formulas

RELATIVE CELL REFERENCE  usual formulas  Cell reference gets adjusted relative to new Location when copied / moved to another cell ABSOLUTE CELL REFERENCE  Cell reference does not change when formula is copied / moved to another cell  Insert $ sign before Column letter or Row number  =$A$1 – Column letter stays & Row number stays RELATIVE CELL REFERENCE  =A1 – Column letter changes & Row number changes

MIXED CELL REFERENCE – Contains both Relative & Absolute Cell Reference  =$A1 – Column letter stays & Row number changes  =A$1 – Column number changes & Row letter stays Using Function Formulas MATHEMATICAL FUNCTIONS – Like calculations performed using a Scientific Calculator  =PRODUCT – Multiplies  =ROUND – Rounds to nearest values  =ROUNDUP – Rounds the value up to next higher value  =ROUNDDOWN – Rounds value to next lower value

=SUM – Adds values in specified cells STATISTICAL FUNCTIONS – Describe large quantities of data  =AVERAGE – Sum of values in selected cells/Number of cells selected  =COUNT - Counts the number of cells with values  =MAX – Shows the maximum value in the selected cells  =MEDIAN – Shows middle values in selected cells  =MIN - Shows the minimum value in the selected cells

Three components of FUNCTION FORMULA:  SUM function: Click AUTOSUM button arrow

ARGUMENT:  Value  Cell Reference  Range  Text  Enclosed inside parenthesis after FUNCTION NAME COUNT FUNCTION:  Click AUTOSUM button arrow  Formula Tab  More Functions  Statistical  COUNT

Using the AVERAGE, MIN and MAX Functions:  The AVERAGE function calculates the average of the range identified in the argument.  The MIN (minimum) function shows the smallest number contained in the range identified in the argument.  The MAX (maximum) function shows the largrst number contained in the range identified in the argument.

Creating Formulas that reference cells in Multiple Worksheets:  The 3-D reference enables you to access data from three different dimensions in the workbook: length, width, and depth.  Length and width refer to worksheet columns and rows.  Depth refers to the ability to connect worksheets by creating formulas that reference the same cell or range in multiple worksheets.  Practice SBS 14.6

 Trouble Shooting Common Formula Errors:  Practice SBS 14.7 ERRORCAUSE / SOLUTION ####Column is not wide enough to hold data. AutoFit the column width #VALUEWrong type of Operand used / Circular reference #DIV/0When Number is divided by Zero #N/AMissing Data #REFCell Reference not valid #NUM!Using Invalid Numeric Value #NULL!Using space when not appropriate
