Question

The thickness of a glass plate is measured to be 2.170 mm, 2.160 mm and 2.180 mm at
three different places. Mean absolute error in thickness of the plate from this data will be
equal to:
1. 0.010 mm 2. 0.005 mm 3. 0.020 mm 4. 0.007 mm​

Answer 1

Answer:

0.0066

Explanation:

mean thickness =(2.170+2.160+2.180)/3

=2.170

absolute error :

|t1|=|2.170-2.170|=0

|t2|=|2.170-2.160|=0.010

|t3|=|2.170-2.180|=0.010

mean absolute error =(0+0.010+0.010)/3

=0.0066
