- The degree of uncertain beyond markings, includes all measured digits and uncertain digits
- All non- zero numbers between 1-9, DO COUNT: Example: 23 = 2 sig.
- When a zero is between 2 numbers, COUNTS as places: Example: 1009 = 4 sig.
- When a zero is to the left of the first nonzero, DO NOT COUNT: Example: 0.0005 = 1 sig.
- When you have a decimal with zeros behind the decimal, DO COUNT: Example: 9010.0 = 5 sig.
- When there is no decimal, the zeros at the end, DO NOT COUNT: Example: 3040 = 3 sig.
- With a scientific notation, only count the significant figures for the decimal: Example: 3.6 x 10^5 = 2 sig.
- Ways to Remember:
- Accuracy:
- How close your results are the the correct answer
- To determine, we look at the average of our results
- Precision:
- How offend the same results are measured or obtained
- To Determine, we look at the consistency or the results
- How to remember?
- Accuracy is when you try to hit the bullseye exactly in the middle, so you try to be as accurate as you can
- Precision is when you hit the same spot in the bullseye over and over again, like you're hitting the middle point every time.
