The correction for guessing in tests with multiple-choice items still a controversial issue, the contribution of literature reveals that more research is needed to investigate and interpret the relationship between the achievement based on partial knowledge and the risk-taking variable in terms of relevant or irrelevant validity when subset selection and penalty for partial guessing takes place. The inclusion of sample questions that have no answer within the test questions is considered as a source of an irrelevant variance which affect the relevant validity. This study suggested a solution for this negative impact by dealing with bidirectional scale. The Operational definition of this scale comes from linking the achievement and risk variables in 7-points. Real data of 64 students and 50 items based on subset selectin method were presented for statistical and logical analysis. The results support the suggested approach for dealing with derived observed scores as if they are two-in-one scale. The statistical results, interpretations, and derived conclusions revealed that this approach is acceptable and promising theoretically and practically in the domain of test Theory, adding a new formula for adjusting the observed scores of the cognitive variable based on the scores of the risk variable.
