Gah dude, what my teacher has to explain to us across multiple days, you do it in 6 minutes

[@marrilynhogg3371]

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!

[@FerretsForever94]

omfg thank you, my ADHD just CAN'T understand when I my lecturer explains it but you guys, it suddenly makes sense ;A;

[@amandakgatinext9836]

Sal sir I can't thank you enough ☺️ God bless

[@alexclausen5480]

This was a great intro to random sampling. How do you quantify the appropriateness of n=30 when p=80?

[@simranara9081]

Thank you so much ....

[@superfastcubing]

what are the types of simple random sample?

[@OurJourneythroughMalaysia]

thanks for this video

[@kam1776]

big help. thanks

[@ibrahimKhan-nl6of]

Good explanation.

[@JohnnyYenn]

Is there really anything such thing as true randomness?

[@s10ihd27]

nice 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?

[@creamblue5990]

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.

Genius

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?

[@ASHOKKUMARVEERASAMY]

You have to pick each item by not looking it one by one. Like he said, put all items in a hat and pick one by one by closing your eyes. In Python you can do it by using simple_random_sample = df.sample(n=100) --> Here df has 1000 rows and you want to pick 100 out of it. This code will pick 100 different items from 1000 items.

[@andrearivera2366]

I think he meant how the sample was decided to be just 30 from the population of 80. I have this same problem. The research committee at my school is questioning how in my research, i stated that I want 100 from a total population of 538. They be like, “what’s the basis?”

[@arkangelnls]

you can't feel names with a blind fold on? LOL and yes, its pretty obvious he meant "cant see the names".

[@szaahhh]

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

[@SnoozingMoose]

Sammi Jo exactly

[@sanket_suryawanshi]

@@szaahhh yes most probably that's what he meant to say

[@julesvthi]

maybe it's just ur grade hahahhuhuhu
