Visualizing Data
Early childhood teachers were being taught how to interpret scores from assessments they administer. The goal in visualizing the data was to concretize it

Sum of scores = 8 + 9 + 10 + 10 + 7 + 6 + 8 + 5 + 9 + 10 = 82
Average = sum of scores divided by number of children = 82 / 10 = 8.2
