Four possible causes of error in a set of measurements are given below. 1 an analogue meter that is viewed from different angles when its scale is read 2 a meter that consistently gives readings $5\%$ too high 3 a meter with a needle that is not frictionless, so the needle occasionally sticks a little 4 a meter that has a zero error Which errors are random and which are systematic?
