Continuity Corrections | ExamSolutions

[@hsstudykaola2459]

I watched multiple videos on this and I didn't understand when it was necessary to use the continuity correction and when not.. This video explains it the best!!! The internet is privileged to have this channel! Exam saver!!!!!

[@silakhan9199]

my teacher explained this to me many times but i did not understand. u really make maths easy, thank u :)

[@ExamSolutions_Maths]

Thanks, that's the aim. Get rid of the mystery

[@tristianzane1010]

a tip : you can watch movies on flixzone. Been using it for watching a lot of movies during the lockdown.

[@willieronald7103]

@Tristian Zane yup, have been using flixzone for years myself =)

much easier to understand with graph, thanks a lot!

[@ExamSolutions_Maths]

No problem. Glad you found it helpful.

[@DHDH_DH]

I watched a couple of videos for this topic and only your video explains everything clearly. You have the super powers to get points across. Saver indeed!!!

[@benphua]

Thank you so much, I really want to pick up statistics but it can be so overwhelming, it is so great to have a source of truth, this comprehensive, explained so well, available freely online. You sir are a hero in my book.

[@Novalax]

This was so much better than my prof's explanation. Thank you!

[@ExamSolutions_Maths]

You're welcome

[@vikeshpatel1764]

This guy is a lifesaver! I don't know how to thank you enough.

[@simplexsettlings9361]

You are a blessing to many. Thank you so much. Love from Africa. Zimbabwe and Mozambique.

[@ExamSolutions_Maths]

Thank you!

[@ExamSolutions_Maths]

Yes. You always use it if you are approximating the Binomial or Poisson distributions to a Normal.

[@beboshi69]

Thankyou a lot. Got full UMS last year in Maths thanks to you, hope I can get an A* too.

[@cindywang8852]

Very clear step-by-step explanation. Thanks for the video!

[@ExamSolutions_Maths]

It can vary depending on what text book you are looking at, and what exam board / exam question you may be doing. In my experience I have come across a wide range of values.

[@TheGheezoinky]

I could just not visualise Continuity Correction at all. Finally you made it so simple. Thank you so much, Cheers!

[@ExamSolutions_Maths]

No problem.

[@franciscodanielquiroz9904]

This is exactly what I have been looking for in the last two months. The thing is that I am making a project about an inventory model called “Fixed period” where one of the assumptions is that my demand has a normal distribution, and since I have the 365 observations of the same object, when I make the histogram, it looks like a Gaussian Bell, so I was so confused, because my Random Variable is discrete but the Normal disteibution is continuous, so I was wondering: how can I treat a discrete distribution with the normal distribution? So, this is the perfect answer to my question: using continuity corrections. Thanks a lot!

[@frazerwilde2646]

thank you so much, just watched all your videos for Unit 4 a-level maths for my exam in 7 hours on 2x speed, really helpful to recap the day before my exam :)

[@ExamSolutions_Maths]

Hope the exam went well. Best wishes.

[@plantastica4622]

Wow!! Finally understood the "include the value" vs. "not include the value." I am not even done with the video. Thank you. Do you have a name? I am sure you do.

[@naheenisapoet69]

he's called Stuart :)

[@ct8463]

Very good explanation. Thank you!

[@piano-fe4bv]

Your explanations make so much sense!! Thank you!

[@fabrizioj.contrerastay9270]

Thank you, that was simple to understand. Now back on studying for tomorrow xd.

[@gauravvasnani2031]

Wonderful video! Helped me understand the concept clearly/

Thank youuu so much! I understand this so much better now! :) 13 minutes well-spent!

Yes - Stuart. Check out my website for further details.

Omg u are so good sir. Thank you so much. I understand the whole concept❤️❤️

[@dreamingqq5078]

thank you sooooo much for this video! It was so helpful!

[@ExamSolutions_Maths]

Thank you for watching and pleased to hear it helped. Best wishes.

[@twfcp1kelvin622]

thx for explaining!

[@longshot-focusgroup9429]

Thank you for explaining this to me. But I was always wondering why they put boxes around the exact value instead of putting boxs between two exact values (say putting box between 27 and 28 for area of probability of 27 and so on). Is it for better approximation purposes?

[@EDGEFEDZ7]

Great explanation! Thank you for your work and insight.

[@paralyzedfruitcake]

If you had to use a continuity correction, would you then use the Normal Distribution to approximate the Binomial/Poisson Distribution?

[@AmIWhatIAm]

Thank you sir!

[@malteeaser101]

Does it have to be binomial or Poisson? Can it just be any discrete distribution that looks normal?

[@pianellrielly9803]

Thanks so much, this is the best!

[@ExamSolutions_Maths]

You're welcome! All the best Pia!

[@nourashraf180]

thank you

[@naheenisapoet69]

I was wondering will the corner of the box poking out of the curve be included for p(x=33) ?

[@ExamSolutions_Maths]

I cannot write it in a KZbin coment but you can see it when you play a video at the start or at the very end.

[@Laughtel-xo8nk]

when u do hypothesis testing do you have to apply continuity correction even if X~Po (7)?

[@ExamSolutions_Maths]

+Rabia Maqsood Yes, if you ever approximate it to a continuous distribution

[@xlaunamx]

Did I mention how awesome you are? Thanks!

[@thewreckedup]

In the Normal approximation to the Poisson, Lambda should be greater than 15, not 20. (general rule) Cheers

[@whatever94ful]

Thank you soo much :)

[@virtuousjoffrey8022]

Good stuff - Fellow Math Whiz

[@plantastica4622]

Stuart can you send me you website link? Thanks.

[@reinaldymaslim]

Do we need to apply the continuity correction for 0?

[@ExamSolutions_Maths]

Does seem a bit pointless as it would be easy to work out without an approximation. I have never come across the need for it but if i had to I would use a continuity correction from -0.5 to 0.5

[@luckyim6504]

oh, that's mean we only use continuity correction when the question changes from bionimal to continuous???? how about the question that given X~N(mean, variance). then do we still use the continuity correction????

[@ExamSolutions_Maths]

No as this is a continuous distribution.

[@luckyim6504]

+ExamSolutions thx help alot

[@luckyim6504]

+ExamSolutions waiiitt.. how do we do the continuity correction when the random variable X is P(X=A)? Is it already done as we expand this probability into P(X

[@ExamSolutions_Maths]

Yes, you can do it that way.

[@luckyim6504]

+ExamSolutions thank you do mucj

[@arunodhinduwara4646]

❤️

[@moshesimon]

The Edexcel Pearson S2 books gives to "simple rules for continuity correction: 1)first write your probability using « or ». 2)for P(x«n) you approximate by P(y

[@ExamSolutions_Maths]

Moshe Simon It's not wrong, that's what I am doing.

[@Saxena981]

For your second last example, shouldn't it be P(X≥ 30.5) ?

[@Karaamjeet]

^^

[@thewreckedup]

Oh then you must be right. :)

[@mahe4102]

For P(X>28) why isn't the continuity correction P(X≥ 28.5) ? Because including 28.5 doesn't round it to 28, right? So why is it ">28.5"? And similarly with P(X≥ 31) --------> P(X≥ 30.5)? Someone help me please! =)

[@SharkKingSeries]

It depends on the sign,not the number.Consider x as a value: P(X>x) it is x+0.5 P(X=x) it is x-0.5 P(X

[@mahe4102]

So basically the continuity correction will only have ">" or "

[@SharkKingSeries]

mahela 27 I was using iPad and it applies to all of them,including the equal to sign.

[@mdaraphiri6767]

is it wrong in your example if l say p(X

[@DedziBlud]

a continuous distribution cannot equal a given amount hence why its continuous

[@TheSunshineRequiem]

@@DedziBlud wrong, for a continuous distribution, they are the same thing
