Gah dude, what my teacher has to explain to us across multiple days, you do it in 6 minutes
Thank you for this. Random sampling is part of my Research module in Social Auxiliary Work. It's sooo awesome to see the theory practically. Thank you again!
omfg thank you, my ADHD just CAN'T understand when I my lecturer explains it but you guys, it suddenly makes sense ;A;
his voise is very soothing i could sleep to it
How do you pick 30 samples? My teacher said I can't "just select" any numbers to be my sample size. I wonder what's the formula for this?
This was a great intro to random sampling. How do you quantify the appropriateness of n=30 when p=80?
Sal sir I can't thank you enough ☺️ God bless
what are the types of simple random sample?
Is there really anything such thing as true randomness?
Thank you so much ....
thanks for this video
Maybe weird question. Shouldn’t you actually put the picks back into the basket to randomly select the next paper? Bc by removing each pick the next pick is no longer as random as the previous bc there will be less names to choose from. If you select the same number again, simply put it back in and try again. Who agrees?

Hi! But isn't it gonna be the same? cuz if you put it back after it getting picked, those will still be no longer part of the papers that arent chosen yet. Because even though there are a lot of paper in there (in the box), the number of names not still chosen will still be the same number.
big help. thanks
Good explanation.
nice video

I think he meant that you obviously can't see, and it works because you can't feel words on a page.
