    Parallax error is an apparent change in an object's position. For example, when reading a measurement off a graduated cylinder, it may vary slightly depending on what angle it is viewed from.

    is this Random error or Systematic?
    if you repositioned your eye to a random position before each reading it'd be random...

    if you kept your eye in a fixed position it'd be systematic - the error would get larger in a predictable way as the angle deviated more from the ideal.

    ideally you'd try move your eye so that the angles were the same for every reading - which is how the old style analogue meters with a mirror scale were designed to be used.

    https://www.petervis.com/avo-meters/...r-reading.html

    so when you're doing a write up you'd mention if there was a possibility for parallax and what you did to mitigate it. Obvs parallax isn't going to be a consideration if you use something like a DMM instead of a analogue meter.
