A person is recording measurements from an analog data reader. During the first reading, he was not looking at the meter from a straight angle. He gets the reading of 72. At a second reading later he looks straight at the machine and gets the reading of 70. a) Which reading number is nearer to the actual value? b) What is the error type that happened in that reading? c) Suppose the data reader becomes faulty due to the extreme heat and gives a third measurement of 65. What type of error happened now? d) The data reader is working properly now, but there is a slight difference between two readings for the same measure. What type of error happened now and how can we minimize it?

A person is recording measurements from
an analog data reader. During the first
reading, he was not looking at the meter
from a straight angle. He gets the reading of
72. At a second reading later he looks
straight at the machine and gets the reading
of 70.
a)
Which reading number is nearer to the
actual value?
What is the error type that happened
in that reading?
b)
c)
Suppose the data reader becomes
faulty due to the extreme heat and gives a
third measurement of 65. What type of error
happened now?
The data reader is working properly
now, but there is a slight difference between
two readings for the same measure. What
type of error happened now and how can we
d)
minimize it?
