I'd like to ask my users a two part question. To categorize each row, and then rank their familiarity with it. However, as is, the side-by-side matrix needs the same scale on both sides.
I've attached an example.
___Categorize Each | Describe familiarity
________ A B C D | Low Med High
Product I...o o o o | o ... o ... o
Product II...o o o o | o ... o ... o
Product III. o o o o | o ... o ... o
