Summary  
This chapter explains how to build compound logical expressions by combining multiple boolean tests with AND and OR functions and embedding them in IF statements for conditional evaluation.

General domain of usage  
Spreadsheet data analysis

In this chapter, we're taking a look at **compound logical tests** using the `AND` and `OR` functions in Excel. 

These functions allow you to perform more **sophisticated logical tests** by combining **multiple conditions**. 

These tools are invaluable for **evaluating** multiple criteria **simultaneously**, making your data analysis more robust and comprehensive.

## Key Points
- Use the `AND` **function** to test if **all** conditions are met like this: `=AND(condition1, condition2,...)`;
- Use the `OR` **function** to test if **at least one** condition is met like this: `=OR(condition1, condition2, ...)`;
- **Combine** `AND` and `OR` functions with `IF` statements for **compound logical tests**.
