Art and Numbers in TinkerPlots
Presented by Vishakha Parvate (KCP Technologies)
Vishakha created some examples of Mondrian/Pollockian looking art using the Sampler from TinkerPlots 2. She engaged users in a discussion about pleasing aesthetics and the like and unlike proportions of the participant colors.

is an appropriate substitute for rolling a fair die. She began by
simulating data for the die using the Sampler and observing its
variability. Then she evaluated data collected from 20 pencils, both as a
whole sample, and then as individual pencils. Finally the entire group
compared the variability in these results to the variability expected
from a fair die, interpreting the results in the context of the
