PPT-Accuracy vs. Precision

Whats the Diff Accuracy Accuracy How closely a measurement matches true or actual values To be accurate only requires the true value the bulls eye and one measurement one arrow to hit . 1 02 03 04 05 06 07 08 09 1 Measured Value of x Fraction of Total Measurements SD 01 SD 02 SD 03 brPage 5br mean standard deviation histogram Figure 3 Mass of Unknown Sample 102 104 106 108 11 112 114 116 118 12 Mass kg of Measurements brPage 6br Chapter 1 Section 2.

In a set of data, those measures give an idea of the spread and “. ballpark. ” of the answer (final measurement).. 1 Accuracy and Precision Notes Chemistry 1 2 Uncertainty in Measurements There is no such thing as a perfect measurement! All measurements have a degree of uncertainty because Instruments have flaws Accuracy of a measurement:. An indication of how close the measurement is to the accepted value. Percentage difference can be calculated to give a quantitative indication of a measurement’s accuracy—the smaller the percentage difference, the greater the .
