This is a brief follow-up video to getting help and it's about finding answers.

The reason why there are two videos about this

is because it's such a critical skill in data science.

So you can see one of the three fundamental sort of,

skills you see in the Venn diagram here is Hacking Skills.

And the reason why it's one of the

three fundamental skill is because almost of none

of the knowledge that you will need is

already sort of set in standardized text books.

It's often scattered in a bunch of different places and you have to be

able to sort of synthesize it or find the information that you need about.

Whether it's about which data set you need to be using, or the statistical analysis

you need to be doing, or the R Package that you need to be using.

All of this is sort of scattered around, and you have to be willing

to do a little bit of hard work and elbow grease to find it yourself.

Obviously we'll tell you as much as we can

in lectures, but we're necessarily limited by the amount of

time that we can lecture every week, and so

it's important to be able to find that information yourself.
