1. Calculate average salary across all employees
| Employee ID | Name | Department | Hire Date | Salary | Status |
| 1001 | Alice Chen | Sales | 2018-03-15 | 65000 | Active |
| 1002 | Bob Martinez | Engineering | 2019-06-01 | 78000 | Active |
| 1003 | Carol Singh | Marketing | 2020-01-10 | 58000 | Active |
| 1004 | David Lee | Sales | 2017-11-22 | 72000 | Active |
| 1005 | Emma Johnson | Engineering | 2021-02-14 | 75000 | Active |
| 1006 | Frank Brown | HR | 2019-09-30 | 62000 | Inactive |
=AVERAGE(E2:E7)Result: 68333.33
The formula sums all six salaries (65000 + 78000 + 58000 + 72000 + 75000 + 62000 = 410000) and divides by 6 to get the average. AVERAGE automatically ignores text and processes only numeric values in the range.
