In addition, self-report (S) and observer-report (O) are sources that usually agree or relate to each other (Cervone, D. & Pervin, L.A. 2013). As a result, the Big Five assessment for this assignment is the collection of self-reported data and observer-reported data to evaluate the accuracy and difference between how I perceive myself and how other perceives me. According to the Big Five assessment, I scored 2.8 for extraversion, 4.5 for neuroticism, 3.4 for conscientiousness, 4.8 for agreeableness, and 3.5 for openness. Initially, I was fulfilled and agreed to most of my results. In my opinion, I think the five dimensions do evaluate my personality well and accurately.
