उत्तर
Two types of errors in measurement are
(a). Random errors-these errors are due to various factors. In a number of observations, we get different readings every time.
These errors can be minimized by making observations a large number of times and taking the arithmetic mean of the readings.
(b). Gross error- these errors are due to the carelessness of the observer like parallax, improper setting of the instrument.
These errors can be minimized only when the observer is careful in setting up of instrument and taking readings.
