Discussion Overview

The discussion revolves around the normalization of data, specifically seeking clarification on methods of normalization in the context of a problem presented by a participant. The scope includes statistical normalization techniques and their application, as well as a mention of the Analytic Hierarchy Process.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant requests help with normalization methods but expresses confusion about the process and seeks detailed guidance.
  • Another participant suggests that normalization can have different meanings depending on context and proposes a statistical method involving Z-scores.
  • Some participants emphasize the need for more context regarding the specific type of normalization required and the purpose behind it.
  • There is a mention of the Analytic Hierarchy Process, with a suggestion that the normalization may relate to assigning weights within that framework.
  • A participant asks for specific methods of normalization to be named, indicating a desire for clarity on the topic.

Areas of Agreement / Disagreement

Participants generally agree that more context is needed to address the normalization question effectively. However, there is no consensus on which specific methods should be used or what constitutes suitable normalization in this scenario.

Contextual Notes

The discussion highlights limitations in the original question, including a lack of detail about the type of normalization and its intended application, which complicates the responses provided.

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
