Elaborating on what Dan said:
Then I'll go hide in a deep hole

I hate when people state, "I need to take a shit."

Clearly, they are not taking a shit, but they are, in fact, leaving a shit.

(Waiting to see how long it takes for someone to point out this reference.)

So if I take six random samples from a data set of over 9000, is it 'the data do' or 'the data does'?

Does. (You're already using it as a mass noun in data set, rather than datum set.)

I wrote a paragraph below to use everything I have learnt, please point out mistakes and Explain WHY they are wrong.

My pet human named JaFF, preffered to eat nuts, rather than eating cats. The nuts--that did indeed belong to moose--were salted. After this happened, JaFF then threw the packet of KP nuts into the garbage. There was silence for a momment; not a single sound could be heard. Then however, JaFF said 'I ate your nuts, I'm sorry. Will you eat mine?' So moose grabbed JaFF's nuts and smiled.

It gives me great pleasure to know that my business statistics teacher - the one who drilled that into my head - has a chance that he is wrong. I love you in the platonic way a married woman call love another man, Richard Nixon's Head.

For the first sentence, you could instead stay, "preferred to eat nuts rather than cats." You don't need to repeat "eating." It just flows better the way I suggested. Also the tense change - using "'eating" after "preferred" - is iffy.

In the second sentence, there should be spaces on both sides of the hyphens. Also, I'd like to make another note here. You set things off in hyphens like you did in this sentence if you want to emphasize what is within the hyphens. If you considered that information to be unnecessary, you would put it between parantheses, like this: The nuts (that did indeed belong to Moose) were salted. There also would be no problem with just using commas here.

The third sentence leaves me wondering why you started with "After this happened." Nothing has happened yet. All you have told us is that Jaff prefers nuts over cats, and then you tell us that the nuts he prefers to eat are salted. But the way you have it phrased, he hasn't actually eaten any nuts yet. So nothing has happened. Moving on, your placement of the word "then" is very awkward. "Then" would more often be used at the beginning of the sentence, like this: "Then, Jaff threw the packet of KP nuts into the garbage."

The fourth sentence seems fine, other than the typo on moment. There's only one "m."

The fifth sentence is messy. First, you're misusing "however." I mean, it's grammatically acceptable, I suppose, but there's no reason to put it there. I would use, "Then," or "But just then," instead. That's unimportant, though. The dialogue punctuation is the real problem. It should be:

Jaff said, "I ate your nuts, I'm sorry. Will you eat mine?" Moose simply grabbed Jaff's nuts and smiled.

I got rid of the "so" because it was awkward. You could also go with something like, "Moose answered by grabbing Jaff's nuts and smiling."

That's everything. Here's a good dialogue punctuation reference to check out. Dialogue punctuation can be really confusing until you get used to it.

Well, that's just a figure of speech.

Oh no you love me more.

Timber?

according to the oxford english dictionary orange and silver govern half-rhymes unlike unstressed rhymes like land & hand and stressed rhymes such as landing & handing a half-rhyme is more of a pararhyme which includes orange & lozenge and silver & salver; half-rhymes contain obvious differences between vowels in certain syllables.

Also pants, whats up with pants and a "pair of pants" its one of the many words in english that has no singular form; the closest you'd get to a "pant" is a "pant-leg" which is a hypenated word...

Well, it is the worst figure of speech I have ever heard.

The dog is hot, and so is trying to pant.

Sure, it's a homophone, but still.
