A researcher measured the percentage of participants who remembered a warning under two presentation formats and two delay intervals.
A researcher measured the percentage of participants who remembered a warning under two presentation formats and two delay intervals.
| Format | Immediate test | One-week test |
|---|---|---|
| Text only | 88% | 52% |
| Text + icon | 91% | 69% |
Which choice most effectively supports the claim that adding the icon had little immediate effect but a larger delayed association with memory?
| Format | Immediate test | One-week test |
|---|---|---|
| Text only | 88% | 52% |
| Text + icon | 91% | 69% |
Which choice most effectively supports the claim that adding the icon had little immediate effect but a larger delayed association with memory?
Answer and explanation
Answer: A: The formats differed by 3 percentage points immediately but by 17 percentage points after one week.
The claim has two parts, little difference immediately but a larger difference after a delay, and A is the only choice that reports both comparisons: a 3-point gap immediately and a 17-point gap after one week. B reports a fact about both immediate values without comparing them to each other. C describes a change in one condition alone, not a comparison between formats. D identifies which format scored higher without quantifying the size of that gap at either time point.
