Hey everyone,

I have just dropped biology and am starting general maths 1/2. Do you think that it will impact my knowledge on the subject by starting a semester later?

Thanks

Wrong page, dude. But, to answer your question, if you're reasonably good at Maths and felt like you were on top of things in previous years (presumably Year 10 Maths), you should not be at too much of a disadvantage. The only problem you would have is catching up on the content that General Maths has already gone through.

If you still haven't gotten it, you could upload it externally and insert it into your post like that. (Try Imgur, maybe?)

Hi

Does anyone know why we use 'centering' when smoothing time series plots?
Like what does centering actually do to the data?

Thanks

Centering is used when using even numbers (ie. 2 mean or 4 mean).

If we have an even number of data values, the value we find will fall between them, hence is not a time point from the original series; we don't want this to happen.

For example, 1 and 2 will become 1.5. However, if we centre the data we are finding the value that will form exactly on that point.

I'm not sure if this has clarified the concept enough for you? Let me know

Why might it be incorrect to assume that braking distance on cars is not normally distributed?

Of course it would be. Remember that a normal distribution takes negative values - can a braking car break a negative distance?

Aha didn't think of it like that.

do you think it's too late to get a statement for the further exams? I think i was deprived of a 50 since i was rank 1 all year and got A+ on all areas of study including BOTH exams, and the rank 3 got a 49.... I know 48 is a decent score, but I don't think i was fairly marked? Cheers

[dankfrank420]

Did you get a exam slip of your score? Not just the grade, but your actual score?

I'd wager that the rank 3 just did better on the exam than you.
