Activity 3.8: Precision Accuracy and Measurement
Conclusion
1. Why is it important to know the accuracy and precision of a measuring device?
Because it lets you know how much room there is for error.
2. Do you think that the dial caliper manufacturer’s claim that the “accuracy” of the instrument is ±.001 is appropriate? Why or why not?
It is appropriate for it to be that accurate because you must also measure other object.
3. Do you think that either of the dial calipers needs to be adjusted in order to accurately display measurements? Explain.
I think it needs to be zeroed out so that you have minimal error.
