The average length absolute error in each observations - 2.482.
The percentage error - 1.69%
Explanation :
Given :
The length of a rod measured in an experiment was found to be :
- 2.48
- 2.46
- 2.50
- 2.48
- 2.49
To Find :
The average length absolute error in each observations and percentage error.
Solution :
Divide the observations by 5 to find average length,
So,
The average length :
The absolute error :
We know that :
So,
Now,
