Precision & Calculating ppt [Example 2]

The video tutorial explains how to determine the precision of density measurements by calculating parts per thousand. It covers calculating the average of data points, determining absolute deviations, and finding the average absolute deviation. Finally, it demonstrates how to calculate parts per thousand and assess data precision based on the result.

How do you calculate parts per thousand from the average absolute deviation?

What conclusion can be drawn about the precision of the data based on the parts per thousand value?

What is the significance of the number 20 in determining data precision?
