Conditional Formatting This allows you to automatically designate

a format for data that fit a particular condition.

Select a range of cells Format => Conditional Formatting

For example, if the value is negative, make the text red

To remove formatting: Format => Conditional Formatting => Delete

You can nest 3 conditional formats

Subtotals Subtotals are useful when data are

formatted symmetrically Dimensioned with multiple categories

This can be useful in many applications Accounting Data summary Reports

Simon, Chapter 3

Subtotals: Subtotal.xls Select entire data block Data => Subtotal=>By month, etc. Explore options

Simon, Chapter 3

Filtering Data

Filtering data allows you to Highlight particular characteristics in the data Identify data elements based on comparisons

to the rest of the data set You can build customized filters that useful

for you routine reports and analyzes. Automates your work.

Scenarios Analysis Excel Scenario Manager helps you

Set up scenarios Explore alternative assumptions Save “what if” results to compare effects

Note: Scenarios change your data. Back up your original data set

Tools => Scenario

IF Statements: ConditionalFormula.xls Cell takes a value determined by a condition IF(logical_test,value_if_true,value_if_false)

Simon, Chapter 4

Additional Information in Chapter 4 Including ranges of data in formulas Tracing formulas

This is useful with complex spreadsheets Looking up values Ranking Amortization tables

NOTE: Chapter 4 is chalked full of very useful information.
