Ted is using counterbalancing to limit order effects. Counterbalancing involves ensuring that each level of the independent variable occurs in each possible position of the sequence equally often. In this case, Ted has created four different orders in which the levels are presented, with each order being used for 25% of the participants. This helps to control for the effects of the order in which the levels are presented, as each order is used equally often.
