Precision means that       ["all", "few", "several", "the average value of", "individual"]  measurements are close to       ["zero", "the accepted value", "the average value", "each other"]  . Accuracy means that        ["all", "few", "several", "the average value of", "individual"]  measurements are close to       ["zero", "the accepted value", "the average value", "each other"]  .
