Explanation:
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.Parallax error mainly happens when the object is viewed from an angle due to the wrong positioning of eye. The first way to curb this error is to orient your eyes in a straight line. Your eyes should be in a straight line directly above the marking on your device, be it a scale or a Vernier caliper etc.
