Q

What are the three essential traits an aspiring data scientist should have according to the speaker?

A

Curiosity, being judgmental, and being argumentative.

59
Q

Why is curiosity important for a data scientist?

A

Curiosity is important because if you’re not curious, you won’t know what to do with the data.

60
Q

Why should a data scientist be judgmental?

A

Being judgmental helps because preconceived notions give a starting point for analysis.

61
Q

Why is it important for a data scientist to be argumentative?

A

Argumentativeness helps because it allows you to take a strong position and learn from the data.

64
Q

Why is storytelling important in data science?

A

Without storytelling, findings would remain hidden, and the data scientist’s prominence relies on their storytelling ability.

65
Q

What should a starting point be for an aspiring data scientist?

A

A starting point should be figuring out the field or industry you’re interested in.

66
Q

How should an aspiring data scientist determine their competitive advantage?
