Hi, why do we use mu,signma in the first graph on heighr distirbution? Because the true population parameters are not known and therefore it is the distribution of height 'samples' right? should X-bar and 's' be used?
One question, the number of experiments (10,000) doesn't have any impact on SEM, right? Intuitionally, more experiments (more sampling) should improve accuracy.
Your videos give the best explanations! You make it so clear and easy to follow. Thank you!
Best explanation I could find. Please keep posting explanations of more statistics concepts. Thank you!
Love ur explanation. I have reached understand u despite my intermedio english. Thnk u so much...
Thank you so much, please keep creating amazing content, love from Vietnam
love it thank u❤

The histogram was supposed to represent the population. Sorry for the confusion.

For each exp, you calculate the SE. The SE will vary between the exp but will not be affected due to more exp unless you combine all exp.
