[biloliddinfarkhodov]

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

[ngl]

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

[fredhasopinions]

Love how an Organic Chemistry Tutor is singlehandedly saving my maths degree

[karlaarana]

here because my teacher is only reading slides and I'm so confused

[ashsaha]

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....

[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

[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"?

[tymothylim]

Thank you for this video. It was clear and easy to follow :)

[aussielife]

Thank you much more simple than my stupid lecturer

[demitrimurray]

Finally!!! Because my school chapters didn't teach me nothing!

[hansanikularatne]

You are the best there is! Thank you!♥️♥️♥️

[a.c.n.]

MY GOODNESS! YOU ARE INCREDIBLE!!!! Incredible! THANK YOU SO MUCH !!!!

[shutdahellup]

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

[sometimes]

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

[Badassboxer]

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

[goldenelegance]

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

[collegeguy]

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

[laxminiharika]

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