Statistics ain't looking good for me ngl

[YourQueenVaslne]

'large data set....oh no..' is literally the reaction i had too when i saw this question

[AlevelStudent-cy]

It’s a little annoying that edexel always put a random 2 marker where we need to have knowledge of the locations of the weather stations Do you have any tips to learn the large data set effectively as its allot of detail? Great video nonetheless !

[AliasAlexandra]

Hi! I think you may have made a mistake! For question 2 part c) you answered in pounds and pence but the question said to the nearest pound! Thank you very much for the video it was super helpfuL!

[benrodman]

How come in the first question you use continuity correction when the question asks for greater than 110( correcting to 110.5) but in the second question when the question asks for all rods with a length >(strictly greater) than 8.09 you don't correct it to 8.095

[nahsee-zqvg]

for the venn diagram question you took the percentage of professionals working in area A but the question states that the percentage applies to professionals who work from both area and B so how is taking the percentage for only area A correct?

[skyeforster]

On question 5 wouldn't it be 40% of everyone who is skilled and 5% of everyone who is elementary because it says in area A and area B. (I know this is wrong but I don't really understand it, so if you could explain a bit further it would be much appreciated).

[sukhysingh]

do some madasmaths, topic questions and some predictions if possible please

[sophiepalmer]

Thanks so much, this is really helpful :)

[liyana]

hi - for q5b, why do we not have the total as the total employees living in area B because the question said they live in area b

[aahad]

Hi Mr Astbury, found your video super useful! Would it be possible for you go over pure Statistics A-Levels papers in future? Thank you!

[KungFuWizardOfJesus]

For Question 4 why did we choose p(X=0) when p(x<1) was closer to 0.025?

[aashiralitaj]

Great video sir 🎉🎉🎉🎉 hope everyone is well guys gl to your exams xoxo😂^_)^😮😢😊

[andreamichelli-lopez]

Mr Astbury, you are a star. Would you run videos for the Edexcel A level Maths 2019 as well? Thank you

[elahejafari]

Sir will you be able to do 2023 paper before the Thursday exam?PLEASEEE

[AlevelStudent-cy]

Hi Sir, For Q3, part d i said “ the probability of it raining in the 14 day period is unlikely to remain constant “. Would this also be a correct answer? Since you need a fixed probability of success for binomial?

[KFCmuncher]

Should we be giving our answers to 3sf or 4dp in general ? (e.g. binomial, normal distribution)

[nectarbee]

If the question doesn't state what significant level it wants the answer to be in, is 3 sig fig alright?

[opic]

How do you know when to put the number in the upper bracket vice versa for normal cd?

[Howtodostuffe]

please do madasmaths papers - there aren't any videos for that
