Question
The four characteristics of big data
Answer
Volume, variety, velocity, veracity.
Question
Which characteristic is about quality?
Answer
Veracity — whether the data is right. Volume does not fix errors, it hides them.
Question
What analytics is used for
Answer
Predicting behaviour, modelling what would happen under other conditions, and understanding past, present and future behaviour.
Question
Why can a bigger dataset be no fairer?
Answer
A group never collected from is still absent, so the blind spot stays while the model looks more reliable.
