Fifteen Questions to Test Your Statistics Knowledge

**Data Minds** are *data producers* (predominantly Data engineers) who *build infrastructure and data products* for consumption by business users or end users.
**Business minds** are *data consumers* of this made-available data that *perform analysis* to aid in business decisions or strategies.
Both of these minds view data differently based on their roles, and their view of data quality is very different, as are their measurement and observations made.
Different personas ( Data Engineers, Scientists, Data Stewards, Data Analysts, etc.) look at the same data through different lenses; however, they still need to come together and collaborate to win.
This support of various personas is foundational and critical for better business outcomes and to enable organizations to become more data-driven.

The classic.
It's built-in, it's reliable, and it's been around for ages.
A true Python staple. 🐍
3️⃣ Mock:
Isolate and rule the world! 🌍
Replace parts of your system under testing with mock objects
and focus on what really matters.
4️⃣ Tox:
Test your code in various Python environments.
Ensure compatibility and make your code versatile! 🌐
5️⃣ Hypothesis:
Property-based testing made easy.
Generate test cases automatically
and put your code through its paces. 🏃
