Define all types of errors.
There
are different sources of error and are classified as follows:
A).
GROSS ERROR:- The human made error
are called gross error.
Example:-
Person using an instrument and recording wrong data may be due to fault in
instrument etc.
The
ways to reduce the gross error is as follows:
1.
More number of readings should be taken.
2.
The reading should be taken after rectifying
the instrumental error.
B).
SYSTEMATIC ERROR
The
error arises due to fault in the system used in measurement.
These
are further classified as instrumental, environmental, observational error.
1).
Instrumental Error- the error due to manufacturing and are inbuilt.it may also
be due to misuse of instrument.
2).
Environmental Error:- these are the external conditions that effects the
measurement of reading for example the pressure. temperature etc.
These
are avoided by taking following measures:-
1).The
equipments free from all clutter.
2).
The arrangement of the experiment should be proper.
3).
Observational error:-the error which is present due the observation of the
reading.
This
can be avoided by taking digital instruments.
c). RANDOM ERROR:- these are the error
that is caused mostly by nature
Example:- sudden change in the weather and these
are also called as residual error.
