Data Modeling
Mystery MixersStudents take samples from a mixer whose
contents are unknown and use this data to determine the location of the
center of the hidden distribution.

Sketching DistributionsStudents
look at the shapes of data and learn to sketch distributions by quickly
identifying prominent features. Students look at plots of different
attributes that demonstrate differently shaped distributions. Students
then are asked to sketch distributions and match their partners'
sketches to the distribution that was displayed.

Building a Data FactoryStudents
create their own data factories that build objects with varying
characteristics. To improve their factory, students consider how values
of an attribute are distributed in the real world.

Fish Length DistributionsStudents
play the role of a fish farmer trying to determine whether the
genetically engineered fish from a new supplier grow to be longer than
the fish he usually farms. They determine whether their results are
valid or just occurred by chance, eventually comparing the conclusions
they drew from the sample data with measures from the entire group of
fish.

Distribution ShiftStudents
explore adding or subtracting a constant as a way to create a group
difference, and explore three contexts that can be modeled using this
additive-shift metaphor.

The Yo-Yo MysteryStudents
analyze data to determine when a break-in occurred at a yo-yo factory,
and then evaluate how close they came to the correct time.
