I have a question about normalization of data

Hello, please help me with this problem. The question is in the picture (LOOK AT THE ATTACHMENT). I don't know how to normzalize the data. How to know which method should be used? I need two methods of normalization here. HELP! Please teach me in detail. You don't have to give me the comprehensive evaluation (final answer) because what I don't understand is the normalization process.

Hey MissP.25_5.

You need to provide a bit more context. Normalization has many meanings depending on how and why something is normalized.

If its statistical, then you would normalize your data by calculating Z = (X - mu)/sigma which gives your distribution a mean of 0 and a variance of 1.

Again, you have to answer what you are trying to do and what question you are trying to answer.

I am guessing you didn't read my question because the question is in the attachment.

I have the read question and it doesn't provide enough information on what kind of normalization and why you should use that normalization. It is too vague for someone not familiar with your problem or field.

You should explain what the analytic hierarchy method is as well.

It only says any 2 methods that are suitable. I don't what is suitable.

Can you name the methods for us?

Apparently this is not a question about standard mathematics, but rather one about the "Analytic Heirarchy Process". (What to call such a things? Other example: "PERT", "Lean six sigma". I suppose they are "management techniques".) Perhaps the "normalization" has to do with assigning the weights mentioned on http://mat.gsia.cmu.edu/classes/mstc/multiple/node4.html
