Understanding Statistical Inference - statistics help

[@Wrenna]

you've just explained something that my textbook has taken 600 pages to muddle up! Thank you :-)

[@DrNic]

That is great to hear. It took me a while to really get my head around it, so it's nice to know my work is helping.

[@govinda399]

@@DrNic namaste i have same feeling.

[@edb3255]

I agree. I found the graphics and speed to be very helpful, and I have to say that the still images of Dr Nic are perfect. To me, they added a human touch to the topic without it being a video that risked shifting the focus to her. Super clever and well thought out, I think!

You have no idea how much I appreciate how simply you explained this!

[@DrNic]

That is lovely to hear. I am currently teaching myself physics with the help of KZbin so I do understand how welcome a well-explained video can be.

[@user-eh5wo8re3d]

This video is a huge help. Many sources simply explain how to use statistics, not how it works

[@chreif]

her pronunciation is excellent which makes the video very easy to digest

[@DrNic]

Thank you! Some people think I have a strange accent, so it's nice you can understand me well.

[@Sats33]

Thanks a lot from India. I have forgotten some concepts this video helped me to get back and explanation is also very good.

[@spellcasterneo]

So, I love math, it was my favorite subject in lower grade school and college. I have recently decided to become a data scientist starting with learning database administration. While examining the career path, I saw that I had to learn statistics, okay no big deal. I am half way through my semester and we started studying statistical inference. My professor, God bless him, is not too good at explaining topics. I have resorted to not attending the class and just read the book. However, the book is filled with unnecessary words. I found this video on the whole chapter and it makes so much sense in just about 7 mins. Thank you so much!

[@DrNic]

That is good to hear. You will probably find some of my other videos useful as well. creativemaths.net/videos/video-how-to-learn/

[@aakashkumar6191]

Thank you ma'am.. I bow down my head in front of you for this kind social charity of information through your videos..🙏

[@DrNic]

It's my pleasure

[@alisonvaughan8618]

Thank you for explaining this so clearly. I am new to stats and this has really helped.

[@DrNic]

Glad it was helpful!

[@Isomnophilia]

I barely passed this module in university... within the 10 years of work and employment, I've managed to filter out distractions and can finally grasp the concept of this subject! I'll recap my studies... i don't use any advanced maths in my work :(

[@DrNic]

Great job!

[@AnFeign]

Best video on statistics I've seen so far. Thank you so much.]

[@DrNic]

Wow, thanks! That is so gratifying to hear.

It is a tricky concept and some teachers seem to make it trickier

[@reznor_prompt2338]

@@DrNic haha, sorry, it's a joke for "in just 2 minutes I got it", I was looking for an explanation like this for like 2 hours and I couldn't find it because all the other classes on this subject focus on math, and that's ok, but I wanted to understand intuitively first, so thanks!

[@DrNic]

@@reznor_prompt2338 I’m happy to hear that. I agree - too many explanations focus on the mathematics.

I got confused about the conculsion at 5: 21 "We are pretty sure that between 32% and 43% of the people think the economy is getting worse". I think it should be 37% instead of 32%. Could you please help me explain this point?

[@DrNic]

Hi - well spotted - you are correct. It should be 37% instead of 32%. Sorry about the confusion from my mistake.

[@riman1035]

Thank you so much ma'am. It was just awesome teaching.

[@DrNic]

Thanks a lot

[@vivekchatt33]

Hi!! Just wanted to know if you have any videos on simulations and how to do it...

[@DrNic]

Sorry - no. We do have a series of videos on probability, that would be useful to underpin simulation.

Wonderful video

[@saraashuri9757]

"I enjoyed watching your video. Thank you."

[@DrNic]

Glad you enjoyed it!

[@M12345-i]

Great video! But your example of New Zealand confuses me. Inferential statistics is about making inferences about the POPULATION from a SAMPLE, but in the example of New Zealand's opinion of the economy, you have what the POPULATION think, i.e. 40% think the economy is failing, and from this you take a sample of the overall population and try to infer how likely it is that 50% or more will think the economy is failing - meaning that you're making inferences about the sample based on data from the population?!

[@DrNic]

You are correct. This is a theoretical illustration to show how we know what are likely results. So if the population proportion is 50% then the chance of getting a given proportion is the p-value. If the given proportion has a zero probability, then we can see that our initial assumption was wrong.

[@laylamonae1382]

[@usamaahmed8635]

sir if I take survey about the popular political party in country and I find that 26℅ people are supporting party A ,36℅ to party B and 19℅ to party C so which type of statistics would it be?

[@DrNic]

It depends on what you are trying to find out. Finding confidence intervals for each of the percentages is a good idea.

[@jiskamulderij9122]

Very good video.

[@DrNic]

Glad you liked it

[@flaviaoliveira5949]

Your videos are very, very good, but I think the example about the population of NZ and the 50% thing, with that graph and all was all a little bit confusing. I chose to ignore that part and the video was very informative, I understand the 3 precepts and all, only that part was not so clear and helpful.

[@DrNic]

Hi Flavia Thanks for the feedback. Quite often with statistical concepts you need to go back over them a few times. Statistical inference is far from intuitive, so if you understood everything else with one viewing, you and I are doing pretty well.

[@tusigapeseta2914]

Yeah I got confused too with the NZ part too, the rest were excellent explanations, very clear - this is my next paper.
