Answer Key

Comparing alternative designs with a criteria table

Section A: Quick Questions

A — List every design in rows and judge each one against the same criteria in columns

B — Easy to read: is the text clear and large enough?

A — Design A: Easy to read 4/5, Easy to navigate 2/5, Looks good 3/5

B — Choose Design A and explain which criteria it did well on

A — I chose Design B because it scored 5/5 for easy navigation, which matters most for young users.

Section B: Match the Pairs

criteria table → A table that lists each design option against the same criteria so they can be rated and compared fairly

Ease of use: Design A = 4/5, Design B = 2/5 → Rating each criterion: giving every design a score for one criterion so they can be compared

Justifying the choice: use the ratings to give a reason for picking the best design → I chose Design A because it scored 14/15, with the top rating for ease of use.

Design A rated on ease of use, Design B rated on colour only → The designs were rated on different criteria, so the comparison is not fair. Every design must be rated on the same criteria.

Total: A = 11, B = 9. I pick Design B. → The choice does not match the ratings, and no reason is given. The design with the higher total (A) should be picked and justified with the scores.

Section C: Definitions

criteria table — A table that lists each design option against the same criteria, rates each one, and helps you pick the best design and give reasons for your choice.

Section D: Fill in the Blanks

Easy to read: A=4, B=2
Easy to tap: A=3, B=3
Total: A=7, B=5

Criteria: read, tap
Design A: read=4, tap=3
Design B: read=2, tap=3

Total: A=7, B=5
Choice: Design A
Reason: highest total score

Total: A=6, B=9
Choice: Design B
Reason: B has the highest total score

Easy to read: A=5, B=2
Choice: Design A
Reason: chose A because it is easy to read

Section E: Spot the Error

A — Both columns are named Idea A, so you cannot tell the designs apart. The second column should be Idea B.

B — The rating scale is 1 to 5, so a rating of 8 is not allowed. It should be a number from 1 to 5, such as 5.

C — Every design must be rated on every criterion. Idea B has no rating for 'Easy to tap'. It should be 'Easy to tap | 4 | 3'.

B — Ratings must use the same scale for every design. 'good' is a word, not a number, so it cannot be added to the total. It should be a number like 3.

B — The best design is the one with the highest total. Idea B scored 9 and Idea A scored 7, so the choice should be Idea B.
