It definitely does do that. Unfortunately, with a textbook online homework platform, they still need to know how to use a random number table

Glad it helped you!

You're welcome.

Thank you!

You're welcome

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

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'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.

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

If it's not for a specific homework problem, yes you can start anywhere on the table.

@@MathandStatsHelp Thankyou very much!

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

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.

You can, but it's much easier to use technology for large selections.

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.

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 ;)

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.

Send your number I have one equation to solve

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.

You're welcome!

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.

You're welcome

You're welcome

It is. You just have to look at three digits and the leading 0 is the same as the 70.

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.
