Central Limit Theorem - Sampling Distribution of Sample Means - Stats & Probability

This statistics video tutorial provides a basic introduction into the central limit theorem. It explains that a sampling distribution of sample means will form the shape of a normal distribution regardless of the shape of the population distribution if a large enough sample is taken from the population.

Been watching your channel for about 3 years now, started as a junior in high school and now im a freshman in college, and you never fail to surprise me with how much you know and teach (:

[@Prospulse101]

Surprisingly, you learned from someone rather than school

[@leticiamal91]

I hope you know how much we appreciate your videos. I’ve watched so many videos, read my teacher ‘s power points, read my textbook and nothing made it make sense like your video! I can’t thank you enough. 🙏🙏🙏

I'm in grad school and you do a better job at teaching in-depth and letting me understand the problems than my professor. I should've watched your videos instead of their lectures

You have been such a help for me this semester!! my professor presents the questions a little differently and one in particular I am unsure how to solve it and not sure if you can assist or point me to the right video where you do them:
"A Random Sample of n=300 Measurements is drawn from a binomial population with probability of success .43. Give the mean and the standard deviation of the sampling distribution of the sample proportion P̂." Thank you for your help!

List the conditions necessary for the CLT to hold. Make sure to list alternative conditions for when we
know the population distribution is normal vs. when we don’t know what the population distribution is,
and the when the sample size is barely over 30 vs. when it’s very large

[@amrhelmy5795]

Thanks alot, your video was so helpful, you always clarify my doubts, I just wanted to ask, why in 57:06 we should use the (-z) table for 0.25, arent we supposed to use the positive one?

[@AkshatJha]

I think what he meant was that you just look up the standard normal distribution table, and find the Z value(Which in this case will be negative) for probability value=0.25. The Z value as per the table comes to -0.675.

At 42:00, in a Uniform Distribution, In this example, you did not have to calculate the height of the uniform distribution.
Since we know that the area of a uniform population distribution is always 1,
In this example, the end points of the distribution are a=21 and b=29
You can get the probability of a single snack bar being between 24 and 26 by simply taking (26-24) and dividing it by (B - A)
= (26 - 24)/(29 - 21)
= 2 / 8
= 0.25
Your method
f(x) = 1/8 when 21
