Practice question · Estimate
An experiment yields five measurements: 10.2, 10.5, 10.3, 10.4, 10.1. What is their mean? Set the slider to your answer.
Estimate on a scale from 0 to 30.
Hints
- Add all five readings, then divide by how many there are.
- The values cluster tightly, so the result sits near the middle of the spread.
Show the answer
10.3 (answers within ±0.309 count)
Why
Mean = (10.2 + 10.5 + 10.3 + 10.4 + 10.1)/5 = 51.5/5 = 10.3.
