6.SP.A.2 Describe a data distribution's center, spread, and shape
Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.
Why water teaches this standard well
Students collect a class's daily household water-use figures and describe whether the data clusters tightly around a typical value or spreads widely, and whether the shape is symmetric or skewed. This describes real household water-use data the same way a water utility describes its customer base.
