I`m new here, and new in the stats world, and i have several questions and need for help on how to proceed.

First, what i`m doing is try to predict an outcome, wich is named Phase in the picture here http://imgur.com/E9MGJQv

What i`m doing is the follow:

1- for every column i`m changing the variables to a scale (EX: 1, 2, 3 etc) with no particular ranking. Question, should this matter i mean, which variable i use as a 1, and which i use as a 6, for example.

2- Im using R to create a model, but how do i know my model is good?

3- Is there any advice on how to proceed? how do i perfect my data so i can have a better model?

Thank you!
