What is Data Science & Analytics?

Data science combines mathematics, statistics, and specialized programming to uncover meaningful patterns hidden inside large business datasets. Instead of relying on gut feelings, data scientists test hypotheses mathematically to understand why past outcomes happened and model what is likely to occur under future market conditions.

In practice: For instance, a subscription company can analyze customer usage metrics to detect which accounts are at risk of canceling 60 days before they actually churn, giving customer success teams plenty of time to intervene and retain the account.
