The absolute difference is the difference between the two measurements, regardless of their signs. In this case, the absolute difference is 76.6 - 70.2 = 6.4 years.The relative difference is the absolute difference divided by the reference value, expressed as a percentage. In this case, the relative difference is (6.4 / 76.6) * 100 = -8.4%.
