Random errors lead to a lack of:
accuracy in the measurement.
significant digits in the measurement.
precision in the measurement.
gradation of the measuring instrument
Which of these is NOT true for systematic errors?
They arise due to errors in the measuring instruments used.
Repeating the observations or increasing the sample size can eliminate them
They are reproducible inaccuracies that are consistently in the same direction.
They arise from the design of the study.
