2.1 Introduction to Data

Data and its Limitations (slides)

Let’s define some initial vocabulary for working with data, as well as start talking about what the limitations of data analysis are.

⊕ data, sample, population, statistics
⊕ types of questions to ask about data
⊕ coverage bias
⊕ transparency & accountability in statistics

Replication Crisis (slides)

The replication crisis is a major issue occurring in scientific fields.

▲ Veritasium: Is Most Published Research Wrong?
▲ 538’s P-Hacking Project

⊕ p-value, p-hacking, replication,
⊕ publish or perish, meta-analysis

We will be revisiting these concepts in-depth later on in the year!
