I’m starting to like stats after watching your videos. Thanks!

"let's hop back to this" - I see you sir

Hi sir, I know it might be a dumb question, but u how some questions say “state whether the relationship between y and x is of the form y=ax^n or y=kb^x? “ how would u know which ones which ? And what is x and n defined as is x just an x then n is a number ?

Like I know how we get Log y = log a +n log x and the log y = log k + x log b and all

Hey sir I’m doing regular maths, in school we are learning discrete random variables, is this something in the edexcel spec to learn

Hello sir, quick question, why can we not use a y on x regression to predict x given y....?

I mean technically why is it not reasonable? Surely we can make a deduction about expected x given y. Your insight appreciated.

At 14:08, You said it will never be zero. How come this is the case ? Also, great vids ive subscribed and pls keep up the content !!

Hi Mr Bicen, can the squirrel question that you mention in the video be found in your Google Drive?

[darainsyed]

For the first question part a cant you just say that the gradient is positive (0.0792) so the colony is growing instead of manipulating the equation?

sir for the first question why did we say g = 10^(-0.2215) rather than e^(-0.2215)

Hi Sir, why would you not be able to use e to anti log that logg on the first example?

hate stats but good video. im still promising that A seb
