1.	What are (i) measurement erroes, and (ii) recording mistakes?
Answer» Measurement Error (also called Observational Error) is the difference between a measured quantity and its true value. It includes random error (naturally occurring errors that are to be expected with any experiment) and systematic error (caused by a mis-calibrated instrument that affects all measurements). Recording mistakes occur when the readings are noted down wrongly. That is writing correct readings in the wrong columns or even writing different readings from the ones taken. This happens either when one forget some decimal points or even interchanges two digits.
