Question

The position of the eye is very important for taking measurements. There might be an error in the reading, if our eye position is not proper. This error is known as ________ error.

Answer 1

Parallax error arises when the reading is taken from a random angle. It is a human error in which the error is due to the perceived shift of the reading when recorded from an undesired direction. In order to avoid this error, the readings should be made by positioning the eyes perpendicularly above the markings.
