Summary
This chapter covers combining boolean functions AND and OR to create compound logical tests and nesting them within IF statements to evaluate multiple conditions simultaneously.

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**.
