Plan your dissertation variables before you start. If you don't control the right factors upfront, you'll slip from a true experiment into a quasi-experiment, which changes everything methodologically. Know what you can actually control before you pick your design.
you want to be able to consider as many factors as possible at the beginning because you may find out you're not doing a true experimental design. You may end up doing a quasi-experimental design because you aren't able to control as many variables as you may need to in an experimental design. You really want to be clear on what you can control. Drop the word "help" in the comments below and I'll send you the link to my free dissertation help community.
