1
CREATING FORMULAS & CHARTING DATA - MANJU

2
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

3
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

4
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

5
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

6
=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

7
Three components of FUNCTION FORMULA: SUM function: Click AUTOSUM button arrow

8
ARGUMENT: Value Cell Reference Range Text Enclosed inside parenthesis after FUNCTION NAME COUNT FUNCTION: Click AUTOSUM button arrow Formula Tab More Functions Statistical COUNT

10
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.

11
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

13
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

14
Using Charts to Show Data:

Practice SBS 14.8 & 14.9
