Answer 1

Accuracy is the degree to which something fits the standard. It is the reliability of what’s being measured.

Precision is how refined that measurement is, or rather how specific, exact, or detailed the measurement is.

Example, accuracy would be how true the reading of a scale is, in that it’s showing only the weight of what you’re measuring without any other interference. Precision would be whether the weight is rounded to 100 kgs, 100.002 kgs, or 100.00240 kgs.
