The Rating System I used a 5 point rating system. 1 being
poor, 5 being excellent.

What I was looking for. How easy is it to use? How easy is it to erase? Which marker am I getting the most
from? This last question I would use as a tie
breaker if need be: Which marker has the best features?

back of the marker? C – How easy is it to pull the cap off the
back of the marker? D – How easy is it to put the cap back

Non-Bias Approach Question A – How difficult is it to push
the marker cap back on the top of the marker?
Question B – How difficult is it to push the cap on the end of the marker?
