EXTENSIVE STEP -BY-STEP GUIDE FOR TEAM ASSIGNMENT 1

CODE, OUTPUT, EXPLANATION, INTERPRETATION & EXTRA TIPS
Note: Original assignment text available at the end.

, MADS MADLAD |2




Note from MADS MADLAD:

Thank you for buying my guide. I sincerely hope it helps you excel and learn
from this course. When I was writing these I sometimes struggled with this
program, but there were no summaries available.
This is why I decided to write something that is truly complete with a lot of
effort put into it. It helped me and my friends get good grades, but I also
always had you in mind, the future reader. When necessary, I always went the
extra mile to make this summary, more readable, organized and complete.
If you feel like it, leave me a review of how the course is going using this
summary, it will make my day to hear your opinion good or bad!

Before we start:

- Clean workspace (optional):



- Load all necessary external packages (using librarian package!):

- Load Dataset & check out the first few rows, get summary and structure:

- Before starting, we also rename our questionnaire variables to more descriptive names
related to the content of the question:




Question 1: What are the factors that can be derived from the many lifestyle and sustainable
clothing perception variables?

- Reduce these two sets of variables into a smaller number of factors, using Factor Analysis.
- Make sure to use standardized variables
- Apply an orthogonal rotation (varimax)
- Include some insights on how the different age categories score on the obtained factors
- Save the factor scores for the rest of your assignment



First, we handle the lifestyle questions (columns 11 to 23 in fashion):

1. Standardize the variables for lifestyle (columns 11 to 23)




2. Before doing checks related to FA, we check if our lifestyle question variables are correlated:




3. Although we are told to use FA, we can check whether it is appropriate by running KMO and
Bartlett (note: the teacher provided the KMO and Bartlett function code):




a. KMO (range: 0 – 1): Our KMO is very close to 1, which is what we want.
