Minimizing Random Errors in Measurements

$|\Delta a_{1}| = |a_{1} - a_{m}|$

$|\Delta a_{1}| = a_{1} - a_{m}$

$|\Delta a_{1}| = |a_{m} - a_{1}|$ (correct)

$|\Delta a_{1}| = a_{m} - a_{1}$

Choosing a smaller magnitude of the quantity to be measured

Using an instrument with a large least count

Increasing the experimental conditions

Taking a large number of readings and finding their mean value (correct)

The middle reading among the 'n' readings

The largest reading among the 'n' readings

The smallest reading among the 'n' readings

The average of the 'n' readings (correct)
