CHAPTER 14CREATING 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, G6Examples 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+C1ORDER OF EVALUATION Multiplication &

Division before Addition & Subtraction =12/6*2 =A1/B1*C1ORDER OF EVALUATION Left------- to ---------

RELATIVE CELL REFERENCE usual formulas Cell reference gets adjusted relative to new

Location when copied / moved to another cellABSOLUTE 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

staysRELATIVE 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 FormulasMATHEMATICAL 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 cellsSTATISTICAL 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

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.

Trouble Shooting Common Formula Errors:

Practice SBS 14.7

ERROR CAUSE / SOLUTION

#### Column is not wide enough to hold data.AutoFit the column width

#VALUE Wrong type of Operand used / Circular reference

#DIV/0 When Number is divided by Zero

#N/A Missing Data

#REF Cell Reference not valid

#NUM! Using Invalid Numeric Value

#NULL! Using space when not appropriate
