Study Notes
Boolean Logic
- Boolean logic is based on Boolean algebra.
- Developed by George Boole in the 1800s.
- Operates on two values: 0 (false) and 1 (true).
Logical Functions
- AND Function: Tests if all combined expressions are TRUE.
- OR Function: Tests if any of the combined expressions are TRUE.
- NOT Function: Checks if a Boolean expression evaluates to NOT TRUE.
Conditional Functions in Excel
- IF Function: Syntax is =IF(logical_test,[value_if_true],[value_if_false]).
- To handle 69 outcomes, 68 nested IF functions are necessary.
Calculation Functions
- COUNTIF Function: Counts cells containing a specific value in a range. Syntax: =COUNTIF(range,criteria).
- SUMIF Function: Calculates the total for a set of values based on criteria. Syntax: =SUMIF(range,criteria,[sum_range]).
- AVERAGEIF Function: Computes the average for a set of values based on criteria. Syntax: =AVERAGEIF(range,criteria,[average_range]).
Reference Functions
- Reference functions allow for looking up frequently used values in a reference table.
- VLOOKUP Function: Used for vertical lookups. Syntax: =VLOOKUP(lookup_value,table_array,col_index_num,[range_lookup]).
- HLOOKUP Function: Used for horizontal lookups, assuming the reference table has been rotated 90 degrees. Syntax: =HLOOKUP(lookup_value,table_array,row_index_number,[range_lookup]).
