=(MAX(B2:B100)-MIN(B2:B100))/COUNT(B2:B100)

Highlight High-Cost Repairs (Over $500):

=F2>500

Formatting and Validation Rules

1. Data Validation (Service Category): Apply a "Dropdown List" validation to the "Service Category" column using the following values: Oil Change, Tires, Brakes, Battery, Engine, Transmission, Suspension, Inspection.
2. Conditional Formatting (Urgent Status): Apply a "Cell Value is" rule to the "Date" column. Set to "Date is before" =TODAY()-365 to highlight services that may be overdue if the vehicle is used frequently.
3. Conditional Formatting (Cost Alert): Set a background color for the "Cost" column using a "Color Scale" (Green to Red) to visually identify the most expensive maintenance events.
