Exactly what I needed!

[@Justice_King]

Very simple but at the same time, very EFFECTIVE. Thanks a lot

[@DrNic]

Glad it helped

[@DingoAteMeBaby]

so far the best ive come across!

[@DrNic]

I am happy to hear that. Thank you.

[@ladycoder2095]

Timely video doc! Can you please do a segment on how to decide which distribution (binomial, Poisson, and normal) to use under which circumstance. Thanks a bunch 🙏🏿.

[@DrNic]

Great suggestion! I was thinking about this myself. I will add it to the list.

[@olivekinuthia5709]

I have this problem too, so hard to know when to use what in a question.

[@megggss]

Thank you for this! Really makes stats easy to learn.

[@DrNic]

That’s good to hear.

[@nilanjana1588]

I got the Poisson distribution now . Video makes it easy to understand .

[@DrNic]

That is great to hear.

[@deepalisangore4816]

Every video of you doctor , is so great and simple to understand and btw Gareth is a really funny name for a cat..

[@DrNic]

Lol. There is a public figure in New Zealand called Gareth who has suggested we need fewer cats as they kill native birds. That cat is named after him.

[@rajshekharghosh2]

Thank you, ma'am.

[@suchitrakulkarni4559]

Great Video. You make is so easy. Thank you!

[@DrNic]

Glad it was helpful!

[@davegoodo3603]

Thanks Dr Nic that was a very clear presentation. ❤

[@DrNic]

Glad it was helpful!

[@jennifergrogan4200]

Thank you so much for your videos. I am teaching from home and I have found these so useful to introduce concepts or for the kids to use as a review. Much appreciated.

[@DrNic]

Hi Jennifer. That is great to hear. What country are you in? What course? I love to hear that my videos are helping.

[@jennifergrogan4200]

@@DrNic I work in an international school in Scotland and teach higher level mathematics from the International Baccalaureate. The course is new to the program and includes a lot of stats which I have taught before, so your videos are also really helpful for me!

[@DrNic]

​ @Jennifer Purpura That is interesting. Many countries are increasing the statistics/data science component of their maths curriculum, which I totally approve of! Do let me know if you find a topic you would like a video about. Can't guarantee it, but it's good to get suggestions. You might consider becoming a channel member for a month or two to help support my efforts. kzbin.info/door/G32MfGLit1pcqCRXyy9cAgjoin

[@shankerbhatt307]

great explanation Doc. Thanks

[@DrNic]

Glad it was helpful!

[@ericstefko4852]

Thanks for all the work you put in to make these very informative videos. Can you help me understand the Erlang distribution? Is it related to the Poisson?

[@henarkzar]

I think I actually understood the poisson distribution after years!

[@DrNic]

Glad to hear it. Statistics can be like that.

[@XxCourtneyBxX]

Ah I just handed in a University assignment on Friday, this would've saved me so much time trying to understand the final question 😂 ah well. Thanks, love your work Dr Nic!

[@DrNic]

Sorry about the timing. You possibly learned it better having to work it out yourself. Thanks for the endorsement.

[@reassume4826]

Great video!!

[@DrNic]

Thanks!

[@analyticstamizan677]

very clear thanks mam.

[@DrNic]

Most welcome 😊

[@trchri]

I am about to finish a university course in probability - this would have been very helpful!

[@DrNic]

Sorry it was a bit late - but I'm glad you think it is worthwhile.

[@shwedontha2607]

Thanks for your great sharing 🥰🥰🥰

[@DrNic]

You are so welcome!

[@Datricky]

great informative

[@DrNic]

Glad you think so!

[@akshaypatil8155]

Hello miss, you have many stats videos. Data science is a booming area in Tech comanies. Could you just group the videos and name the playlist something like 'Complete Stats for Data Science'. For syllabus of stats in data science, you can refer online. Their are many websites or even youtube videos for it. This will also help you rank your videos on youtube. You are really good at teaching. simple examples makes it very easy to digest. Thanks and good luck

[@DrNic]

Thanks for the suggestion

[@KiranVarri]

beautifull explanation 🤩👌👌👌

[@DrNic]

Glad you liked it

[@funwithwords632]

nicely explained

[@DrNic]

Thank you for that.

[@ayazab3150]

Nicely explain i enjoy, but i wanted to know about my horse performance and it's stats

[@DrNic]

ok?

[@callforlove2361]

Hello. Dr.Nic. Please, could you answer on my question. Do you provide services in analysing and writing biostatistics report ?

[@DrNic]

I could do. Email me at n.petty at StatsLC.com

[@sainath1736]

Madam correlation regression and curve fitting using Excel ..... Pleaee Teach Madam

[@DrNic]

Thanks for the suggestion. I will add it to my list.

[@sainath1736]

@@DrNic Thank you Madam

[@DrNic]

Have you seen these two? kzbin.info/www/bejne/hZnTYoOmr9eFnqc and kzbin.info/www/bejne/g5LCqnaNgL5-e8U They are about regression in Excel.

[@YarkoFFXI]

Please take this as constructive criticism, but I hate when maths concepts are explained like this. You explain how to USE the model but not HOW it works, so one must memorise pieces of information without really grasping the fundamental concept. And one will be forever wondering whether they are applying this model to the correct cases or not. In my opinion, the proper way to teach such a topic is by starting with a concrete problem we need to solve, e.g.: model the rate at which people arrive in a queue. Realise these are independent events because the arrival of one customer is not influenced by the arrival of other costumer. Then, from this concrete example, explain how to build a model like Poisson. That means explain exactly how to define lambda, how to calculate probabilities for any N, etc. Without using pre-made tools like excel, otherwise I will never understand what's going on when I ask excel to calculate this for me. This is the only way of teaching that will teach you when it's proper to use Poisson model,because you are actually understanding the model itself and not just applying it blindly.

[@DrNic]

Thank you for taking the time. I am cognisant of all you say and agree that for many people your approach is helpful. However, I have found that some people learn by applying - and I am certainly one of those. A highly-esteemed statistics educator once said "Mathematical understanding is not the only understanding." The other thing is that this is a KZbin video, not an entire course in statistics or probability. For people who are struggling, this can be helpful. Feel free to make videos of the type you describe.
