Differentiate between precision and accuracy.














just know it's something to do reliability and validity... have to turn the index card over...

[md90]

Precision--reliability--consistency and reproducibility of a test; there is an absence of random variation in a test; random error decreases the precision of the test;

Accuracy--validity--how true is the test measurement??? TP + TN / N; if there is a systematic error, then there is a reduced accuracy in a test.
