Matrix
Rate several statements (rows) on the same answers (columns), like a Likert grid. On phones each row becomes a card.
Every plan
- Rows (statements): 1 to 30, such as Price, Quality, Support.
- Columns (answers): 2 to 12, such as Poor, Okay, Good, Excellent.
- Several answers per row: checkboxes instead of one answer per row.
- Randomise rows.
When the question is required, every row needs an answer. On a phone, the grid turns into one card per row so nothing is cramped.
In logic, a matrix compares how many rows were answered.
