Wow😊 you really saved me...my exams nearing and was worried about sampling 💪👏
THIS IS THE BEST VIDEO IN THE HISTORY OF RUclips!!!!
Thanks a lot for this detailed explanation.
Hi. I know that on a TI 83 or 84 your can set the random seed. This way all of you students will produce the same random numbers. ex 3894 sto Rand (You get to pick the number part and give the number to your students.) Also, most software lets you set the seed also.
It definitely does do that. Unfortunately, with a textbook online homework platform, they still need to know how to use a random number table

Awesome explanation! Great job and thank you!
Glad it helped you!
Omg you just saved my semester test mark!😭
You are the best! Thank you so much for the explanation
You're welcome.
It's good explanation I like it. Your professional one
Thank you!
Thank you maam..... you teaching it very easily 💓💙💓💙
You're welcome
This is very incredible, keep up the good work.
Thank you
@@MathandStatsHelp please can we communicate privately? I had a project to carry out which deals with clusters sampling, I have little or know knowledge on how to set up my data..
Thank you
Thank you for the vid, sometimes mystatlab doesn't do a good job at explaining!
Really thank you l was in trouble situation ❤❤
This seems like a dumb question, but how did you choose Row 2 Column 3 as your beginning point? Is that just your random choice, or did something else inform that decision?
Thanks!
It was just a random choice.
@@MathandStatsHelp Great! Thank you! I've been an engineer for 17 years now and never utilized a random number table before. I figured at some point it was a matter of closing your eyes and pointing to the table, but I didn't know about the method of running across the row ignoring spaces to get the next values. This video was very helpful!
I remember using a similar table in the '90s. Makes me wonder how these numbers were generated. The book I used was likely published before computers became ubiquitous. Without a computer, did someone pull chits out of a bag to generate the pages upon pages of randomized digits? I shudder to think.
The tables in the 90s were similar to this table. Here's a little history courtesy of Wikipedia : en.m.wikipedia.org/wiki/Random_number_table
thanks for teaching easily
Good video 👍
Thank u very much ❤❤❤❤❤❤
May I ask when picking your respondents from the Random number table can you start anywhere you want?
If it's not for a specific homework problem, yes you can start anywhere on the table.
@@MathandStatsHelp Thankyou very much!
I was just wondering as our statistics teacher linked this for a project. If the amount of students was 100, would the value still be 3 digits, or 2?
It would be 2, because you can use 00 for 100. 00-99 is 100 digits.
@@MathandStatsHelp Thank you so much for your quick answer
Thank you~
Thank you
Where did you get the random numbers?? Please answer my question.
This excerpt was from the text I teach from. There are random number tables online or in the back of most stats textbooks. For homework problems, typically they give you in excerpt in the problem.
@@MathandStatsHelp I thought you got it from excel where u are going to copy and paste some formula.
Thanks a lot for this content.
I have a question -
1. How do you get these 5-digit number?
The numbers are an excerpt from a random number table. You can find random number tables online and at the end of most Statistics textbooks. If you are in a Stats course, most of the time the specific table is given in the homework problem so that everyone gets the same result from the same table.
@@MathandStatsHelp Thanks a lot for your reply.
Currently I am admitted into a 36-credit Master Program of Applied Statistics and Data Science. Prior to it I did not have any kind of statistical background. Now, I am going through the first semester. So, things are very new to me.
Thanks again, for your reply. I will write to you again.
Wishing you good luck.
I hope your masters program goes well.
@@MathandStatsHelp Well, great that you asked. Honestly, I am struggling a lot and this study program is bringing my past back again in this present.
I studied Public Administration in my bachelor and Masters level quite a long ago. And, we did not have to learn any quantitative issues in detail. So, I did not studied.
Now. the only backup is that I had all the quantitative/scientific courses in all my academic years until the end of higher secondary level (18 years of education) where I just could not remember any relatively complex processes at times of the examination. And now, in this present course, relatively easy quantitative processes seems to be hard to remember.
I will just have to try harder.
Like your video but I can't help to conclude that you contradict yourself in your open. You say no one uses random tables anymore because it's tedious but then you explain that it's the easiest way to pick a random sample. So is it easy or tedious?
It's the easiest way to guarantee that all students on a test pick the same random sample for ease of grading. In the real world, it's much better to use a random generator to gather the sample. The textbook/classroom world isn't always the same as the real world.
Thank you 🙏
Send your number I have one equation to solve
What about the researcher wish to select 35 students to 2500 populations can i use 4 digit is it possible? Or i only use 2 digits?
You can, but it's much easier to use technology for large selections.
Could you please help me to find the answer of that question “Select 50 students out of 200 students using the simple random sampling”
I'm not sure what you are asking for. If you had to do this in the real world, you would most likely let technology select the random sample. Are you supposed to do it with a random number table? It could take a very long time to get 50 people selected with a random number table.
@@MathandStatsHelp I supposed to use random number tables, but like you said it take too much time, I think I should find another way to solve that question, thanks for your reply ;)
Thank you. Understood
You're welcome
Aren’t we supposed to go down and not horizontal?
I've always gone across. Most homework platforms are programmed to go across. If your text tells you to go down, then that's what I would follow. You just want to make sure that you are following the technique that you will be graded with.
Excellent
hi there, can you please explain the Replacement and Without Replacement concept????????????????????
Replacement means that after drawing the item out and seeing what you get, you put it back into the container or deck of cards before selecting the next one. With replacement keeps the amount of items the same. Without replacement means that you select an item and don't put it back. You now have one less item then you did before. Hope that makes sense.
Thank you
Understood. 🙂
You're welcome!
I LOVE YOUUUU❤
Why I didn't start to choose from start of numbering rather than 3row
You can start randomly anywhere on the number table. You could start at the beginning, but sometimes texts tell you to start in a certain row or column, so I just wanted to address that.
Thank miss
You're welcome
Very nice madam. I love you 😘
excellent accent
83 06
I thought 070 is the same as 70 .
It is. You just have to look at three digits and the leading 0 is the same as the 70.

Wrong procedure!
There is no need to ignore any number
You don't if you have exactly 100 or 1000, but otherwise you do. If you only have 335 people who are assigned a number from 001-335, if you get the number 562, there is no person to select, so you have to ignore it.
