A star plot allows us to compare various aspects of a single observation that would not benefit from the averaging of numerical data. In this particular case we are able to see a single starplot comparing the judgements of a team to the actual test score of the student, per section of the test. There are five different test elements, each of which are represented as a radius from the center of the starplot, and include Letter identification, Hearing and Recording, Concepts about Print, Word Reading, and Writing Vocabulary.
