4. TIP: Accuracy = Actual What is Accuracy?
DEF: The accuracy of a measurement is how close a result comes to the true measurement.
TIP: Accuracy = Actual

5. In the picture you see 4 darts are all close to the bulls eye but not to each other.
They are ACCURATE because they are close

6. What is Precision?
Precision is how well the values agree with each other in multiple tests.
IE: How close your measurements are to EACH OTHER

7. Precision
The 4 darts are not close to the bulls eye BUT they are all very close to each other.

8. ACCURATE AND PRECISE
DARTS ARE ALL ACCURATE – because they are all in the bullseye
DARTS ARE ALL PRECISE –
Because they are all very close to EACH OTHER

9. ACCURATE AND PRECISE
Measurements can most definitely be accurate and precise! This simply means that ALL of your measurements are close to the “correct” or “actual” measurement.
