T214 2011 Block 1 Sections 1-8

Hi All

Just thought I would add another tab to allow T214 2011 students to identify discussions about Block 1 a bit easier. :D

Hi Michele!
When you wrote
I have never used this program

were you referring to this forum or to which program?
Sorry for being dense.

Hi All,

I'm on T214. Waiting for my TMA01 score. I haven't been understanding all the Power Law stuff too well. I'm worried that I'm not Level 2 material but I'll keep going. What put me off was that section having all that maths. I break out in a cold sweat in the face of a big ole sum with Xs and Ys in it (and apparently, Ks too, who knew).

I hope to hang on with my fingernails any way.

Elaine.

hello! hang in there it gets a lot easier, the power law stuff is but a small part of the whole...don't worry and good luck with the TMA01 score...

i think <scratching deep in memory> that the only thing you need to 'take away' from the power law stuff is the idea that small things can escalate/run away/suddenly get a lot bigger...that a few connections each having a few connections, leads to a lot of connections...small changes can make big differences...

well that's about all *i* remember about it anyway!! :)

if you have a thing and you add another thing, that's two things and one connection.
if you have ten things and you add ten more things, that's twenty things and a Lot more than ten connections.

I think there has also been an increasing recognition that while Gaussian distributions do occur widely and can give insight where they are appropriate the name given to them, (normal), can be a bit misleading.

IE if you are examing a phenomenon with the expectation that a 'normal' distribution is in place, when in fact a power law relationship would be more accurate, (and vice versa) it can lead to very wrong conclusions.

Also as more people have begun looking for power law relationships they have found that they crop up all over the place, which again somewhat undermines the 'normal' tag given to gaussian distributions.

I wouldn't get to hung up on the maths, but the importance of the implications of how we expect to see things affects what we see should be stressed.

Hi Elaine,
You are certainly level 2 material.
Many of us have now passed level 3 and still don't know the equation governing a power law.
I suggest, as the others have also done, that the "take away" is easier.
Many things are grouped with an awful lot at one end and a long tail.
When you see or suspect this distribution you realise that covering 20% of the options is often good enough.
If you cover 20% of the options 80% of the people will be happy. The other 80% of options will make everyone happy but you will probably run out of whatever before you get there.
Keep at it. It doesn't get easier but it doesn't get harder either.
Have fun
