Data Aggregator
Sub Trajectory: Data
Classifies objects that may be perceptually different by more abstract attributes such as function or conceptual attributes. Focuses on features of the data set as a whole. Uses to describe relative frequency and density (shape), and location (centers). Begins to understand the concepts of expectation (averages and probabilities) and variation (“spread” of values).
Understands ranges in data or the mode (the number that occurs most frequently). Eventually, can focus on features of the data set as a whole, including the relative frequencies, density (“shape”), and location (centers, such as the mean).
