Since the effect of sag is to make the measured length too large, it is always subtractive. E.g. ASHRAE Guideline 14-2002. Yahoo Public 31053 - Speed N Saves | Fantasy Baseball | Yahoo! Sports Thanks,Taft. Yes, it is. Systematic Errors Systematic errors, or biases errors, result from the physical properties of the measuring system. W = wt of tape b/w supports, This correction is required when the points of supports are not exactly at the same level With the advent of online gaming, casinos are now global and accessible to everyone. Cs/ = Sag correction per tape length. unit, Nominal length: The These errors are dependent on the observer, the instrument used, and on the physical environment of the experiment. Not a term you hear too often with respect to your measurement systems. Correction for sag is the deference in length between the are and its chord i.e b/t the curved length of the laps and the distance between the supports. probable errors in base line measurements - zacklinedinst.com Suppose instead of 20 times, we measured the same sample 5000 times.
