**What is the precision rule?**

The precision of the measurements refers to the spread of the measured values. One way to analyze the precision of the measurements would be to determine the range, or difference, between the lowest and the highest measured values. In that case, the lowest value was 10.9 in.

**What are the 5 rules for significant figures?**

Significant Figures

- All non-zero numbers ARE significant.
- Zeros between two non-zero digits ARE significant.
- Leading zeros are NOT significant.
- Trailing zeros to the right of the decimal ARE significant.
- Trailing zeros in a whole number with the decimal shown ARE significant.

### How accurate are rulers?

Distances are normally measured with a ruler. The limit of accuracy of a ruler is indicated by how “precisely” you can read the length on that ruler’s scale—that is, how well you can estimate between the marks. On the portion of the ruler shown in Figure1, the distance between the closest marks is 0.1 cm.

**What are the rules of significant numbers?**

To determine the number of significant figures in a number use the following 3 rules:

- Non-zero digits are always significant.
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion ONLY are significant.

**What is the error of a ruler?**

More “precise” measurements can be made on the first ruler. The greatest possible error of a measurement is considered to be one-half of the measuring unit. If you measure a length to be 4.3 cm. (measuring to the nearest tenth), the greatest possible error is one-half of one tenth, or 0.05.

## What’s more accurate than a ruler?

Vernier caliper is an instrument that is used to measure internal and external dimensions and distances. Vernier calipers can measure accuracy to one-hundredth of a millimeter and one thousand of an inch. With a vernier caliper, you can make more precise measurements than you could with regular rulers.
