The correct ranking method for these scores involves assigning the highest score (120) the rank of 1. The next two scores are both 110, so they share the average rank they would occupy (2nd and 3rd), which is 2.5. The last score (105) is ranked 4th. This method ensures that each score is appropriately ranked relative to the others, including handling ties by averaging their ranks.
