Consider this statement: "The variation between groups was 3.7%." Is this statement discussing accuracy or precision? Briefly explain why you chose your answer.
Homework Answers
The above statement refers to precision. In general, accuracy is defined as how much close is the measured value to a given true value. Whereas, precision refers to the variation in measuring the same part repeatedly using the same instrument. In other words, precision expresses the degree of reproducibility.
