Business Intelligence (BI)
▪software that searches vast amounts of data to derive information for improved decision making
▪ IF function displays one of two possible values depending on the outcome of a logical test
▪Logical Test compares two things
▪ If the Logical Test equates to TRUE, the cell is filled with the True Value.
▪ If the Logical Test equates to FALSE, the cell is filled with the False Value.
IF Function

▪ Use the IF function to assign the label of easy or hard based on the hours. If a course requires more than 3 hours of study time per week, we will label it HARD. Three or less hours of study is labeled EASY.
IF Function Example
▪What cell is used for the logical test?
▪What is the logical test?
▪What is the true value? False value?
IF Function Example
3
▪LOOKUP functions display one of MANY possible values depending on the outcome of a logical test.
▪Often used to translate one value into another value.
▪Requires a lookup table.
▪Lookup Value is compared to Lookup Table
▪Can find Exact Match (false) or next closest value (true)
VLOOKUP Function
http://www.lacoste.pamplin.vt.edu/web1504/resources/video/ss.html
▪First column must be used for logical test.
▪First column must contain a value, not a range of values.
▪First column should be in ascending order.
Lookup Table Rules
Lookup Directory Example Solution
1. F1 is compared to first column of lookup table.
2. Extension from Column 2 is displayed for match.
3. False means an exact match must be found.
Spreadsheet Design: Efficiency
▪All calculations, including comparisons, should be done by the spreadsheet.
