How to work it out
- Gap between the values: |69 − 79| = 10
- Average of the values: (69 + 79) ÷ 2 = 74
- Divide the gap by the average and multiply by 100: 10 ÷ 74 × 100 = 13.5135%
- Check: Work backwards: 0.135135 × 74 = 10, the gap between the values.
In a spreadsheet: =ABS(69-79)/((69+79)/2)*100. Dividing by one of the values instead of their average turns it into a percentage change, which depends on which value you start from.
