The Learning Goal for this assignment is: Determine appropriate and consistent standards of measurement for the data to be collected in a survey or experiment.

Significant Figures Rules There are three rules on determining how many significant figures are in a number: 1. Non-zero digits are always significant. 2. Any zeros between two significant digits are significant. 3. A final zero or trailing zeros in the DECIMAL PORTION ONLY are significant. Please remember that, in science, all numbers are based upon measurements (except for a very few that are defined). Since all measurements are uncertain, we must only use those numbers that are meaningful. Not all of the digits have meaning (significance) and, therefore, should not be written down. In science, only the numbers that have significance (derived from measurement) are written. Rule 1: Non-zero digits are always significant. If you measure something and the device you use (ruler, thermometer, triple-beam, balance, etc.) returns a number to you, then you have made a measurement decision and that ACT of measuring gives significance to that particular numeral (or digit) in the overall value you obtain. Hence a number like 46.78 would have four significant figures and 3.94 would have three. Rule 2: Any zeros between two significant digits are significant. Suppose you had a number like 409. By the first rule, the 4 and the 9 are significant. However, to make a measurement decision on the 4 (in the hundred's place) and the 9 (in the one's place), you HAD to have made a decision on the ten's place. The measurement scale for this number would have hundreds, tens, and ones marked. Like the following example: These are sometimes called "captured zeros." If a number has a decimal at the end (after the one’s place) then all digits (numbers) are significant and will be counted. In the following example the zeros are significant digits and highlighted in blue. 960. 70050. 21
