My screw gauge shows a positive reading when fully closed. What correction should I apply?

That nonzero closed reading is a positive zero error.

How should I use a graph to find an experimental constant reliably?

First rearrange the physical law into y = mx + c and decide what each axis represents.

What does “Least count and instrument reading” actually mean in Experimental Skills, and why does it matter for NEET?

An instrument cannot honestly resolve changes smaller than its least count. A final reading combines the main-scale reading, coinciding-division contribution, and the zero-error correction with correct sign.

I keep getting “Least count and instrument reading” questions wrong in Experimental Skills. What's the trap?

adding a positive zero error instead of subtracting it from the observed reading.

What does “Accuracy, precision and uncertainty” actually mean in Experimental Skills, and why does it matter for NEET?

Accuracy means closeness to the accepted value; precision means repeatability. Repeated measurements can reduce random uncertainty but cannot remove a systematic calibration error.
