yeah im not going through grade two atp
bienayme tchebychev type shit, i had that on my final exam last year, aced it icl
ngl i lost it all, i dont do stats this year i forgot everything, and i aced the stats part cuz i got lucky, for the whole year i didnt understand shit to stats
for the whole year i didnt understand shit to stats
das what im saying cuz!!! this shit incomprehensible
but trust if u just listen in class even if you dont understand, somehow, it will click in your mind in front of the exam paper, at least it did for me
but trust if u just listen in class even if you dont understand
oh about that..... i.... already passed that phase..... and i didnt even participate alot and tried to figure out my self....
i disagree, the random bootstrap method is pretty nice, but it's not ALL of statistics
maybe this can help
idk
https://en.wikipedia.org/wiki/Statics
didnt have that topic yet
its statistic not statics i just say it cuz i forgor the difference
sadly its not that interesting
can you atleast swap ur german brain to mine cuz im getting fried with those prob
my german brain hasnt expierienced the topic of calculating statistics yet
my best advice though is to not overthink it
to not overthink? u serious? cuz im not overthinking shit and the problem gets worse n worse dawg
The random variable X has a normal distribution with mean μ and variance σ
2, i.e.X ∼ N(μ, σ2). It is known that:
P(X ≤ 66) = 0.0359 and P(X ≥ 81) = 0.1151.
(a) Produce a clearly-labelled sketch to represent these probabilities on a normal curve.
(b) Show that the value of σ = 5.
(c) Calculate P(69 ≤ X ≤ 83).
brotato how am i suppose to solve ts
https://www.physicsandmathstutor.com/maths-revision/a-level-edexcel/statistical-distributions/
Look at the cheat sheet for chapter 3, year 2
See if that helps
I can maybe help, but only the relatively basic stuff like binomial and other distributions
search up Sample correlation coefficient i was praying to every religions god at ts to make me understand
Pmcc or srcc?
I see correlation coefficient and I have neuron activation
Srcc is just ranking the data and then subtracting the 2 ranks, then you square them and add them all together. Then you use that value, multiply it by 6 and divide against (the total number of samples cubed - total number of samples)
Pmcc is basically S'xy/(S'xx multiplied by S'yy)
S'xx is basically the variance but not divided by n yet
Correlation coefficients will go from -1 to 1 and 1 means strong positive correlation i.e. as x increases, y also increases, -1 is strong negative correlation, 0 is no correlation
Use savemyexams or physicsmathstutor trust, they should have something on pmcc and srcc
The actual S'xx formula is = (sigma (x^2)) - ((sigma x)^2/n)
I took stats 1 in college and ngl it was like you describe it or even worse maybe, good luck with that
most of the shit you learn is basically useless you won't even see it at exams unless you're taking advanced statistics classes
yk ur cooked when mf says unless and says sm shit that is prob what im doing in future
lmao sorry if it sounded aggressive, what I meant to say is that you'll study so much stuff that most likely will never see again. dw statistics is an interesting field to study, im sure you'll do great
statistics is the best kind of math. def clears c0culus 3 and l0n0ar algebra
Linear algebra is not that bad
Except for when I can't use gasussian elimination and have to use transpose and find determinant
its not that the classes is hard. its more that i think statistics is the most fun
Ye I acc find statistics the most fun icl, it's just therapeutic finding the solutions to stuff and analysing
+1
stat is just the most useful
linalg has some nice applications in random places, but yea Ive never directly used it outside of uni
And ana.... idek wtf Im meant to do with that shit
brother statistics are like 𓂋𓇋𓂧𓂧𓃭𓅂 𓇌𓅱𓅲 𓎢𓄿𓈖𓏏 𓅲𓈖𓂧𓅂𓂋𓋴𓏏𓄿𓈖𓂧 𓄿𓈖𓇌𓏏𓉔𓇋𓈖𓎼

I dislike them too but theyre genuinely useful (like using R studio or sum, not doing stats by hand)
