The two dot plots below represent the scores of students from two classes in the most recent grade test.
Without performing any calculations, which class has the greater MAD?

Plan and conduct surveys and experiments using the statistical enquiry cycle:– determining appropriate variables and measures;– considering sources of variation;– gathering and cleaning data;– using multiple displays, and re-categorising data to find patterns, variations, relationships, and trends in multivariate data sets;– comparing sample distributions visually, using measures of centre, spread, and proportion;– presenting a report of findings
Evaluate statistical investigations or probability activities undertaken by others, including data collection methods, choice of measures, and validity of findings
