Your explanation of the continuity correction is so clear. As a former math teacher, I've really got to commend you on this video.

@ExamSolutions_Maths 10 лет назад

Thanks

@yen0607 3 года назад

Sir you've been my main math help since my O Levels and now I'm a 2nd year university student still finding myself going back to your videos, thank you so much for your outstanding explanation of various topics that have made math so much simpler!

I was so confused about how Binomial Distributions could be used in Normal Distributions. This video clarified all my doubts! Thumbs up!

Thanks! You solved my headache.

@ExamSolutions_Maths 5 лет назад

Aspirin works better I thought. Many would say this brings on a headache! Pleased to have cured yours though.

@LikeStig 12 лет назад

Thanks for posting this. Put a smile on my face when I began to grasp it. Classes should be taught this way.

@rafiatbm7867 5 лет назад

Thanks a lot sir....Was having great difficulty in continuity corrections but two of your tutorials (which includes this one) has helped a lottt...

@ExamSolutions_Maths 5 лет назад

That's good news. Best wishes to you.

crazy that this video is 11 years old but still the best one I've found for this

@kennethnyongesa6899 9 лет назад

@vbscootychick 10 лет назад

You are amazing! Seriously the best maths teacher I've ever heard. I have my Year 13 Stats exam in two days (from NZ) and I know this will help me greatly :)

@aleeshahsohail8012 3 года назад

i have a stats mock soon and this made everything so clear thank youuuuu

@bootsofescaping01 12 лет назад

Thank you, your explanations are very thorough.

@thecraftnest 11 лет назад

Thanks so much!! I was really struggling with continuity corrections before watching this ...

@graemeskinner6283 11 лет назад

Much thanks, was struggling with this concept but this video made things very clear :)

@Hamromerochannel 2 года назад

That’s was so great way to teach and understand contnuity correvtion

@seantakunda909 Год назад

How do you handle a situation where x is a decimal like P(x

@ExamSolutions_Maths Год назад

simply has to be smaller. P(x < 40.5)

@ChrisOfTheInternets 10 лет назад

After one year of statistics, and with my S4 exam tomorrow morning, only now have I really understood continuity corrections. Why teachers in classes cannot explain things as clearly as this I will never understand!

@McRackin 12 лет назад

Thanks for the video. Awesome supplement to any first year stats course.

@serenajoywrigh94 12 лет назад

you literally just helped me pass my exam

@pubgkidshooter 4 года назад

@humairaprince2794 6 лет назад

Thank you so much for helping with continuity corrections, I had absolutely no clue how to do them before watching this video so I really appreciate it!

@ExamSolutions_Maths 6 лет назад

No problem, pleased to hear it helped.

@ExamSolutions_Maths 11 лет назад

Excellent

@alaynas2335 2 года назад

Thank you sooooooooo much!

@ExamSolutions_Maths 12 лет назад

I like that. Keep smiling.

@timedwards100 12 лет назад

but p.s. you are the only reason i hope i will pass!! so much appreciation for what you do and all your help!!

@thenextjeymar8658 6 лет назад

i'm struggling to understand how you achieved 0.9 in the tables. What and where did you look up?

@behram87 5 лет назад

From the normal distribution tables. Google it

@williamewen6716 5 лет назад

Perfectly explained. Thank you!

@ExamSolutions_Maths 5 лет назад

Thank you

@erinmrollins 12 лет назад

thanks..this was helpful.

@aravrajesh6286 2 года назад

Is it possible to calculate the probability without using the Z-Transform? Can't I just do Ncdf with mean = 12 and std = sqrt(7.2)?

@wasekbd 12 лет назад

very well explained

@abanerji265 3 года назад

Thank you soo much for this.

@muhammadazeem1346 5 лет назад

Great .... needed you at class today ... where were you?

@ExamSolutions_Maths 5 лет назад

Sorry I couldn't be with you I was here having a great time.

@kovaMOO 12 лет назад

thx :) studies which poison my existence seem less insidious now..

@naheenisapoet69 3 года назад

hello, could u tell me which of ur playlists this is in?

@kglian 12 лет назад

good explanation, tks.

@Joel-wt4lm 6 лет назад

So I know I'm kinda late to the party but is it mainly based on which side of the mean the value lies? And if so, how do you know which way to round if the mean is unknown in the question? (so you don't know which side of the mean the test value lies)

@demetriusdemarcusbartholom8063 6 лет назад

It was really helpful.

@tedtdu 12 лет назад

How were your tutorials made Sir (e.g. equipment, software etc.)?

@johnsonahiamadzor7404 2 года назад

Very great

@yingyang9482 2 года назад

Thank you

@alainlee2159 4 года назад

I'm still confused if we use the calculator I get a different answer after finding for the z probability I don't know if I should use the normal cd or the other method P

@yoometh 12 лет назад

Thank you do so much!!!!!

@XICrAvEIX 12 лет назад

When can u upload the rest of the s2 vids please??

@bruceg.2517 5 лет назад

you are the best

@ExamSolutions_Maths 12 лет назад

Not at all. You can never equal a value with a continuous random variable.

@MrSuhailjan 7 лет назад

nice explanation

@willsonbasyal7883 8 лет назад

Now, I'm gonna take the Maths out of my teacher...

@ExamSolutions_Maths 12 лет назад

Thanks

@tedtdu 13 лет назад

@youtube. you guys should invest people like him so that we do not pay to schools, where we learn nothing but wasting time

@SorryCrane16 8 лет назад

When X is greater or equal to 13, why is Y not greater or equal to 12.5 but just greater. Surely Y greater or equal to 12.5 would in any case be also equal to 13 as it's supposed to. (Sorry if it's hard to understand I can try to use symbols on request)

@SorryCrane16 8 лет назад

13:10 for reference

@ExamSolutions_Maths 8 лет назад

+John Fletcher Greater than or equal is not going to change the final solution as you are dealing with a continuous random variable. However, you can never equal a particular continuous r.v. For example it is impossible to draw a line that is 5 cm long. The line you draw may well look like 5 cm but may measure 5.0000123734 cm. Who knows? My point is that you can never have equals to when working with continuous random variables.

@SorryCrane16 8 лет назад

+ExamSolutions what you said makes a perfect sense to me it's just that I was baffled because in the Edexcel S2 textbook in some of the examples they have used the greater to or equal sign in the continuity corrections. I'm learning all of S2 only with the help of a textbook and it's quite a challenge because some of the stuff isn't explained in detail at all.

@ExamSolutions_Maths 4 года назад

No you don't. Best wishes.

@jameshulse8559 8 лет назад

ExamSolutions How come you couldn't just use the binomial table from the beginning as X~B(30,0.4) is within their ranges isn't it ?

@ExamSolutions_Maths 8 лет назад

The point behind the video was that I was showing how the Normal distribution approximates a Binomial distribution when certain conditions are met.

@jameshulse8559 8 лет назад

ExamSolutions Ahh I see, I was worrying there was another reason for why you wouldn't be able to use the tables, brilliant video however, fully understand what you're trying to get across, great job!
