In science, uncertainty refers to the precision of your measurements. No matter what instrument you use the last figure you write down is the figure with the uncertainty. A burette is carefully manufactured to measure volume but the manufacture knows that there will be some uncertainty - the burette can be read with confidence to with in 0.1 mL. That means that the volume reading 25.3 ± 0.1 mL is correct. When a calculation is done with this volume the uncertainty is converted to a percentage uncertainty. The scientist understands that every measurement has some uncertainty in it and this uncertainty is contained in any answer. When the answer is written down it must take account of the uncertainty of the measurements. When calculating the calculator may have 8 figures in the answer but these figures are meaningless if the the starting figures were uncertain after the 3rd figure.
I'm not entirely certain.

∙ 9y agoLet's say you have one brother and no sisters. No one else lives at your house besides your parents. Your toy comes up missing. You have a high degree of certainty your brother took it. But at school lunch you left your purse, you have a high degree of uncertainty about who specifically took it.

That is the correct spelling of "suspense" (anxiety, uncertainty).
What is a synonym for ambiguity?

Is density an exact value by definition?
No. D=m/v and no measurement is exact due to uncertainty.
What are words that mean confuse?
Chaos, pandemonium, uncertainty.
What does the acronym FUD mean?
Fear, Uncertainty, Doubt
How do you measure uncertainty?
To measure uncertainty, you need to know the precision of the instrument, which refers to the smallest unit that an instrument can measure. A measurement can then be represented with its associated uncertainty, such as X = (5 +/- 1) cm. In this case, the actual value can deviate from the mean (5cm) by 1cm, so the minimum and maximum values ate 4cm and 6cm respectively. The percentage uncertainty is calculated by (absolute uncertainty / mean value) * 100%.
What are other words that mean confusion?
Chaos, pandemonium, uncertainty.
What does the Heisenberg Uncertainty principle mean?
In any measurement, the product of the uncertainty in position of an object and the uncertainty in its momentum, can never be less than Planck's Constant (actually h divided by 4 pi, but this gives an order of magnitude of this law). It is important to note that this uncertainty is NOT because we lack good enough instrumentation or we are not clever enough to reduce the uncertainty, it is an inherent uncertainty in the ACTUAL position and momentum of the object.
Is the standard error of the sample mean assesses the uncertainty or error of estimation?
yes
Identify three types of uncertainty when you run a business?
There are three types of uncertainty when owning or managing a small business. The three types of uncertainty are state uncertainty, effect uncertainty and response uncertainty.
How do you calculate uncertainty?
There are several ways to calculate uncertainty. You can round a decimal place to the same place as an uncertainty, put the uncertainty in proper form, or calculate uncertainty from a measurement.
What is uncertainty?
Uncertainty is not being sure of something.
What means uncertenly?
You could mean either uncertainly or uncertainty. One is adverb and the other is a noun.
