Calculator to find probabilities for normal distribution
Here we look at using the Casio fx-991ES Plus scientific calculator to work out probabilities for the standardised normal distribution using the functions Q(z) and R(z) built into this calculator.

P()----> Area less than z value
R()----> Area greater than z value
Q()----> Area between 0 and z value

[@MagicalDanny]

If anyone is wondering how to do something like P(-2.8 < Z < 1.4) = 0.9167
the step for that is shift stat/dist, distribution, p, then do P(1.4)
then do the same for P(-2.8)
The final answer is whatever value you get for P(1.4) subtracted by P(-2.8) which should end up being approximately 0.9167

THANKS SO MUCH!!!!

thank you so muchhhh!!!!

thx Danny

God bless you

[@prosimulate]

...And when I saw the table in the stats lecture I thought, yeah right there has got to be a better way, all that messy interpolation. My exams are 8 weeks away and I will become a Jedi Master in this...Presentation wise you are absolutely spot on. I don't know why the heck the tables are needed. Am I going to do the Exam on the same island Tom Hanks was stuck on in Castaway, yeah throw in the abacus while you're at it. lol!

[@mikebabz]

No you don't need an abacus, Just come with your table and chair 🤗

[@tri-hun-fri]

Thank you! There are almost no videos on using this calculator. Your awesome!

[@97MrOmar]

Thank you man you're work is sick and is helping me a lot

[@hassan010012]

Thanks! I'd like to ask a question, please! How we use the calculator to calculate the z-score if the probability is given?

[@princeemma-ejikeme2622]

Still helping till now...
Thanks a lot 👍
Prepping for my Statistics examination tomorrow morning

[@LOISLANE99999]

thanks that was a good explanation. Im taking a data class and this helps!

[@jayso9135]

Good video...really helpful

[@dorsmovies]

Got a question, Is there a way to do the function Qnorm in the program R, which shows you percentages before a value?
For example Qnorm(0.1) is -1.281 because 10% of the area under the graph is before -1.281.
This is the opposite of p(-1.281) that will give me 0.1.

[@samgirl964]

Thankyou for this amazing video!

[@ExamSolutions_Maths]

That's okay. Thanks for watching.

Can u please tell how to use t distribution table in calculator

[@anaisalonso2036]

how do I get the z0 (inverse) with this calculator?

HOW DO I USE THE CALCULATOR TO FIND T VALUES, CAN YOU PLEASE SEND ME THE VIDEO WHICH EXPLAINS IT

[@aashika9792]

how to use both plus minus sign at a time

[@WanSyazlina]

now i understand how to find the probability. but how do i find the n value on x axis if the probability is given. for example: P(Z>n) =0.3015... how do i find n using a calculator? without using a probability distribution table

[@tgdhsuk3589]

i dont think u can

[@RehanAli-of3my]

hi, can you tell me how to calculate slope on different points?
lets say i have eqn " y=25.655+0.575x " i have 10 values of x. how can i do it in my fx991es plus?

[@manavnair7688]

Use differentiation in your calculator

[@ezraowns]

Please do as many of these tutorials with this calculator for S1 before the exam on the 10th please.

[@Eskimoose]

I agree, this was really useful and I can now see that are loads of useful functions for stats, please make more tutorials! :)

[@aman___004]

How was the exam and what you're doing in life now? :P

[@shivadarshan8682]

Thanks a lot

[@ExamSolutions_Maths]

🙂

[@mathew_pang]

ExamSolutions Can I know how you put the calculator into the video?? I really want to know how! =)

[@binness]

if you think you have the brain power to do maths, then you must know how to find it.

[@random-accessmemory9201]

It is an emulator.

[@hamzahanif661]

Ymx+c how to calculate inverse normal distribution in casia FX-570Es nd Fx-991Es plus

[@CristianoRaashid77]

binness knowledge and wisdom are two different things, although related.

[@CristianoRaashid77]

Google it. Casio scientific calculator for PC.

[@subhodeepsinha7890]

But how to get the inverse of this in fx 991 es plus?

[@krishnakaul3887]

Does anyone know any website where we can use this digitally?

[@sujanthapaliya2032]

Thank u..

[@ExamSolutions_Maths]

Thank you for watching. Glad you got something from it.

[@benedictr4181]

hey , can you do poisson distribution for s2 with this ? if so a vid would be brilliant . PS you are my hero

[@barneyy6942]

What is the use of fourth one?

[@surajnair9757]

can i find value of z(normal variate) if i know the probability!?

[@sophiem285]

This video just saved me

[@GiacomoMana]

great video, hopefully I pass algebra 2

[@sohailjanjua123]

Hi I like your video

[@darklord2909]

Any idea how to enter this question. “ on investigating The labour efficiency an organisation is found that there is typically a favourable mean of $65000 and a standard deviation of $5000.
What is the probability that the variance is less than $45000?”

[@londonthokchom4968]

is it possible to make a video on finding the "z" value given the probability? Thanks for this video, really helped a lot!!!!!

[@ExamSolutions_Maths]

Only for this calculator where you set the mean to 0 and the standard deviation to 1 www.examsolutions.net/tutorials/inverse-normal-function/?level=A-Level&board=Edexcel&module=Statistics%20A-Level&topic=1840

[@rushivyas3648]

Thanks so much. Now I don't need to carry normal distribution table

[@bienbatallones7269]

Need help if the given is the area and u will find z how?

[@muthukumaranas.k.8687]

thanks sir

[@ExamSolutions_Maths]

Thank you for watching and I am pleased it helped.

[@AbdullahiIdri2001]

Why not just use the Normal C.D function and use the values of the SND? It gives identical answers and I'm assuming I wouldn't lose marks as all the working out is done via calculator anyway.

[@dondodo2130]

what apps did you use bro?

[@ExamSolutions_Maths]

This is a Casio Emulator which you purchase from Oxford Calculators

[@SamikshyaGaire]

I want to know how to save area formula in this calculator plz can some one help me?

anyone know how to get the 5 number summery from this calculator because mine only shows min & max

That's okay. Thanks

[@olgapriiutova1701]

Thanks a lot. Have you use a ONLINE graphing calculator? Could you be so kind to recommend the application?

[@ExamSolutions_Maths]

This is a Casio emulator available from Casio

Hi, can you tell how to see t value from fx991ms

[@ditipun7052]

U can't bro

[@ciaranhession6920]

We can always calculate these without the calculator, right? Mine doesn't have the functions.

[@philipshergold4771]

Does the Casio fx-85GT PLUS have the 'Distribution' calculation type?

[@AegisMU]

Hi did you ever find the distributing function? £25 seems a lot to get a new calculator because mine is missing one function

[@ChurroCinema]

@@AegisMU Did you find it?

[@AegisMU]

@@ChurroCinema nope had to buy a new one. Theyre not too expensive used on ebay though 😌

[@ChurroCinema]

@@AegisMU Damn my exam only permits the use of the casio 85 model

[@urielortegabotello4092]

Does anyone know how to do problems where it’s like: "What Z value has an area of 0.9706 to its right?"

[@ismailmuhammedabdulle3172]

You need tables to answer such :(

[@macronelmacron7133]

How can I find Z when I already have the probability????????

[@random-accessmemory9201]

Macron Elmacron you compute it using calculus.

[@akashanil4540]

z = (x - μ) / σ

[@vocassen]

You'd want the invert function of this, which the calculator does not support, so you'd be back to using tables
