Why the distribution of data in samples is important (with examples).

Describes how to interpret data with multiple peaks.

Explains and exemplifies bivariate data.

Explains how Google Maps and Waze use big data to optimize a user's route via the immense amount of data collected by constant tracking. This clip also describes how City Brain uses big data to optimize traffic.

Explains how big data can have unintended consqequences. The example used illustrates how big data used the presence of snow to categorize huskies vs. wolves, even though this is not what the researchers wanted the algorithm to learn.
