## Skedasticity and Finiac

Skedasticity is a measure of deviation from the expected results of a particular data set. This is useful when looking at the performance of a financial asset because it tells you a lot about the volatility of that asset.

Volatility, for us, is a core metric that we use to think about potential investments.

We favor histograms, like the two examples in the graphic above.
