Reaction-time lab
Wed, Mar 17, 2027 · Week 9 · Human Anatomy & Physiology (Human Body Systems)
Today's goal: Measure reaction time under different conditions and record the data.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Method: ruler-drop, distance converted to time in milliseconds. Five trials per condition.
Baseline condition (no distraction):
- Trial 1: 210 ms
- Trial 2: 195 ms
- Trial 3: 205 ms
- Trial 4: 380 ms (flagged outlier: fumbled catch, excluded)
- Trial 5: 200 ms
Baseline average (excluding outlier): 202.5 ms
Distraction condition (counting backward aloud):
- Trial 1: 265 ms
- Trial 2: 280 ms
- Trial 3: 255 ms
- Trial 4: 270 ms
- Trial 5: 260 ms
Distraction average: 266 ms
Which was slower: the distraction condition was slower by about 63.5 ms.
| Trial | Baseline (ms) | Distraction (ms) |
|---|---|---|
| 1 | 210 | 265 |
| 2 | 195 | 280 |
| 3 | 205 | 255 |
| 5 | 200 | 260 |
| Average | 202.5 | 266 |
This model shows the level of evidence and organization needed to complete: A reaction-time data table recording multiple trials in a baseline and a distraction condition with units, condition averages computed, and any outliers flagged with a note.
- Name the variables and include units.
- Enter observations without changing the raw values.
- Check labels, calculations, and patterns before interpreting the data.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Submit your completed data table.

Claim ceiling: Today's evidence supports a classroom claim about reaction-time lab. It cannot prove causation, diagnose a real patient, or justify action outside this room.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Collecting reliable reaction-time data and handling outliers.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
