Question

A science student takes 100 observations in an experiment. Second time he takes 500 observations in the same experiment, by doing so the possible error becomes –

• A. $\frac{1}{5}$times
• B. 5 times
• C. Unchanged
• D. None of these

Answer 1

Answer: (A)

$\frac{1}{5}$times

Answer 2

If number of observations are large, then average deviation

or possible error µ $\frac{1}{no.ofobservation}$
