Thank you very much!

You're very welcome Larissa, glad you liked it!

Good stuff Joachim, I think this is basically the same process as generating Z values by "normalizing" the data.

See your other comment :)

Thank you so much for the video and explanation. in fact I have a problem with my dataset and I tried to apply your syntax for rescaling and it did not work. I have two ordinal indicators that measure the same dependent variable and I wanted to create an index that combines both of them. Both are ordinal variables that range from very high to not at all. The problem is that one indicator has a 1-5 scale and other from 1-10. I tried to rescale the smaller one to be 1-10 scale and it did not work unfortunately. don't know what to do. I wish you a merry Christmas and happy new year. Many thanks :)))

Hey Mahmoud, thank you for the very kind words! :) Could you share the code you have used so far, and the output that it has produced? Merry Christmas and a happy new year to you as well!

Hey Joachim, :) I have a small question: I have a set of variables I am using to create an index, three variables have the scale from 1-4, other variable from 1-7, other one from 1-8 and other one from 1-10. Since they are all having different scales, I decided to rescale them to the highest, so from 1-10. It worked and I have the cronbach Alpha value of 0.85, but I noticed that this statement is written in the R Console exactly before the results of chronbach Alpha: "Number of categories should be increased in order to count frequencies." I tried to ignore it sicne everything is working so far so good with the index and the regression analysis, but I wianted to check what does it means and if it is a serious problem or so. Thank you sooo much :))))))

Hey Mahmoud, unfortunately, I'm not an expert on chronbach Alpha. However, I have found this thread on Stack Overflow, which discusses this warning message: stackoverflow.com/questions/65113692/r-lack-of-cronbachs-alpha-information I hope that helps! Joachim

Hallo, I am trying to write here a comment of my code but it is always unfortunately deleted. I don't know what is wrong with the youtube :((((

Hey Mahmoud, this is strange, I also cannot see it in the spam folder of the comments. Could you try to post your comment once again?

@@StatisticsGlobe Hallo Jochaim, I hope this time it works. Thank you so much for your concern :)) I used the folloing code : Happiness

[@StatisticsGlobe]

You are very welcome! :) Maybe the function "rescale" is overwritten by another package? Does it work if you use the following code? Happiness

@@StatisticsGlobe I believe it works now😊😊I do not really know how to thank you for your help and concerns😍Das is sehr lieb..Ganz ganz vielen Dank☺

I have a small question again sorry :( if the old score is progressive (like from low to high) the new scale will be the same or? and is it possible to change change the change the scale like to make it progressive or descending (from high to low) ? Many thanks :))

[@haraldurkarlsson1147]

I realize that Z of course normalized with mean and stdev so it is not the same.

[@StatisticsGlobe]

Yes, it's a slightly different approach :)
