The Learning Goal for this assignment is:<br />
Determine appropriate and consistent standards of measurement for the data to be<br />
collected in a survey or experiment.<br />
Notes Section:<br />
Zeros aren't ALWAYS significant figures, just sometimes.<br />
When they are in scientific notation, you only look at the base numbers.<br />
*** Zeros after decimal points aren't significant unless there is a<br />
number before the decimal.<br />
For ex..<br />
.000034 is not significant<br />
however<br />
1.000034 Is, because the zeros are between two non zero (therefore significant)<br />
figures.<br />
Another example,<br />
345000 - these zeros are not significant, they are just place holders. they're not in<br />
between two non zero numbers.<br />
To add/subtract<br />
you have to figure out how many significant figures do these numbers have after<br />
the decimal place<br />
You don't need to go further than the least ammount of decimal places.<br />
For ex.<br />
2.84+6.77896=9.61896<br />
You would only need to write 9.61 because 2.84 only has 2 sig. fig. after its decimal<br />
place. Thats how precise you have to be<br />
