Question

What do you mean by accuracy and precise and what are the error that might occur while calculating them?

Answer 1

Accuracy refers to the deviation of a measurement from a standard or
true
value of the quantity being measured. We can talk about the
accuracy of a
single measurement.
Precision tells us how close a group of measurements are
to one
another. The closer the data replicates, the more likely the
results
will be similar in the future.

The types of errors are:
personal error, method error and instrumental error.
