I could never understand my professor explaining this. You are saving my exams!

[@biloliddinfarkhodov3956]

You are the one who can explain hard topics in simple and easy way!

I'm here because it's an hour before exam and I haven't learned anything from school

[@erinroxmyjox]

This was such a great video! Much clearer than my uni text book. Thank you for sharing and clarifying

[@iiisapphire]

you learnt this in college??? I'm learning this in highschool wtff

[@erinroxmyjox]

Sapphire Maye ok bit judgemental coming from a teenager who thinks they know everything, but let me assure you, you don’t. I know because I was a teenager once. You should probably learn to be less judgemental and more humble

[@iiisapphire]

@@erinroxmyjox i meant that it sucked that i had to learn it not saying that i was better than someone else for learning it earlier um but i see how it came off that way... :/

Good explanation! Exactly this is what I am looking for...and thanks to youtube the very first video I got when searched... Conceptual Approach is depicted in this video....

no one covered this before thank you!

[@pacezhuo5377]

谢谢！

[@mermaidfinn]

okay but how do they apply to the same set of data? if i'm not given any information at all regarding the size of the population, how could i calculate the population mean compared to the sample mean? what's the difference beside the "N"?

[@touheedkhalid3412]

Actually you are asking about another term called "inference". currently teacher is describing only "descriptive". So if you wanna learn about it, keep watching videos. within no time you will be able draw inferences from the sample statistics.

[@jamkiol]

@@touheedkhalid3412 that was the worst response you could've possible gave

[@touheedkhalid3412]

@@jamkiol Okay. thanks for the input.

[@izumiasmr]

​@@jamkiolin my opinion that actually was a very good response, one that we actually should take as a good example! In descriptional / inferential statistics there's actually a conceptual barrier that is better not taken up lightheartedly and is better to be approached slowly, which in the case of watching KZbin videos, perhaps even doing so in a haste, is better to be done in the course of several days, without fast jumping into the inferential matters.. so tauheed's answer's importance cannot be overestimated!

[@JohnArrowShorts]

I have a request. If possible can you further elaborate what is the difference between parameter and statistic. Also can you explain detail by detail what and how those formula got arrange in that way (the one with SUM and Xi and i=1.) Thanks in advance

[@shutdahellup69420]

so the sample mean is always going to be different based on the 100 people we picked for our sample right?

[@goldenelegance94]

How did you choose 100? In a data set ex. 20,24,50,60,80 , how would you choose wha the sample is?

[@RandoPassingBy]

in a small data set as in your example, I believe that a sample is unnecessary because it is easy to navigate the entire data set. He chose 100 NUMBER out of 100,000 NUMBER, because getting 100,000 NUMBER of people to do a survey and collect data is almost impossible. Hence, he assumed that there is a survey that was handled to 100 NUMBER of people, and use this result to predict the distribution data for the 100,000 people in total. Or, at least that's my understanding and memory from high school XD It has been ages since my last time doing stuff with statistics, or else I won't be here for revision

Dude didn't you forget to say little n is n-1? or am I wrong? what did I miss

[@cfothough]

I'm still kinda confused on how to go about finding the mean of my sampling distribution based on what is basically yes or no questions, I didn't keep track of when people would say yes or no but instead the numbers of yes and no responses I got. I had 29 yes responses out of 118 people, and I'm really not sure how to go about finding a mean from this. Any help would be extremely appreciated!

[@liliamartinezl8327]

U Solved your problem?

[@cfothough]

@@liliamartinezl8327 I think I was able to, I got an A on the project I needed help on lol

[@Badassboxer147]

I learned the sample size. Still lost on population size. Or at least how it applies to my current problem.

[@lindandungu5670]

[@collegeguy799]

Can you explain why books say x bar is equal to mu? That makes no sense

[@harvestcrops3983]

So basically it's the same formula but different meaning to the letters.

[@moyo5443]

I love you.

[@fatimahaidari4314]

Are they equal to one anoher tho orno

[@KartiKM001]

Thanks :)

[@laxminiharika4116]

Why is population mean named as Mu-bar, isnt it just Mu?

[@ashleighhutchinson7170]

you didnt solve it at the end tho

Hello Mr.dear, can you help me, please?

[@JoseFernandez-qt8hm]

N = 100,000; pop = (x1 + x2 + x3 + ... + x100,000)/100,000. so why do n when you already know N????

[@trident1409]

n represents sample of the population and N represents the entire population. watch the video carefully.
