For instance, if your business was worth $1,000 at the beginning of the month and it’s worth $1,200 today, you’ll calculate growth rate with 1,000 as your starting (or past …
How to Calculate Uncertainty
If your experimental measurement is 60 cm, then your uncertainty calculation should be rounded to a whole number as well. For example, the uncertainty for this measurement can be 60 cm ± 2 cm, but not 60 cm ± 2.2 cm. If your experimental measurement is 3.4 cm, then your uncertainty calculation should be rounded to .1 cm.
