A music streaming company evaluated the performance of five playlist interface layouts using data from eight different user groups. For each layout, the company measured the satisfaction rate—the percentage of users who rated the layout as “easy to use.”
The table shows these satisfaction rates for each layout and user group.
For each of the following statements, select True if it can be verified from the data provided. Otherwise, select Not true.

Official Solution:
• Exactly two layouts have the same median satisfaction rate.
To find each median, the satisfaction rates for each layout are sorted, and the median is the average of the 4th and 5th values.
- Card grid: median = (22 + 24)/2 = 23
- Compact list: median = (23 + 25)/2 = 24
- Horizontal scroll: median = (22 + 24)/2 = 23
- Minimal tiles: median = (20 + 21)/2 = 20.5
- Dynamic feed: median = (25 + 26)/2 = 25.5
Card grid and Horizontal scroll both have a median of 23.
Answer: True
• Exactly two layouts have the same range of satisfaction rates.
Range = highest value − lowest value.
- Card grid: 31 − 14 = 17
- Compact list: 34 − 17 = 17
- Horizontal scroll: 27 − 15 = 12
- Minimal tiles: 30 − 16 = 14
- Dynamic feed: 33 − 20 = 13
Card grid and Compact list both have a range of 17.
Answer: True
• Exactly two layouts have the same highest satisfaction rate across all user groups.
The highest satisfaction rate for each layout is:
- Card grid: 31
- Compact list: 34
- Horizontal scroll: 27
- Minimal tiles: 30
- Dynamic feed: 33
All five layouts have distinct maximum values.
Answer: Not true
