[uhoh]

[psychologycodes]

Thank you!!!! All of your videos have been a blessing!!! Will be reporting when I get my A* in maths!

[rthraitor]

thank you! re looking over stats since it was so forgettable for me, however you explain it really well and manage to make it far less boring hahah

for 16:16 my first thought was that could you do the area between 75 and 80, and then do 0.4 - that area to get the area of b then inverse normal

Hi sir just wondering in 10:20 you calculated the IQ by doing 1-0.3 so you used the left tail area of 0.7 for your calculation. Does it not work if you just use 0.3 but use the right tail when you input it onto the calculator? Thank you very much for your useful vids!

[M-ov]

Hi how do you know where to put that a value? Like on the left hand side or right hand side. Thank you.

Hi sir, just wondering if you have the graphics calc and can put central tail or right tail, do you still need to show working and pretend your calc can’t do this to get the marks haha?

Hi Sir, am I allowed to use my CG50 Graphics Calculator in my Mathematics A Level exam? I do not take Further Maths so will only be using it for normal Maths. I've found varied answers on google where some people say yes, others say it's banned.

[marceledeko]

So for the first examples are we basically guessing that a is greater than 20?

[alijabbar]

What's that calculator you're using?

[christopherforbes-jones]

I do fm and recently got the graphical calculator you use in your video but I have used the other calculator for the last year and hence am more familiar with stats on that calc, is it worth familiarising myself with stats on fx-cg50 or just using both for different functions
