Basically your uncertainty is the innaccuracy or your measurement. For instance if you had a yard ruler that was marked only in inches and the length of the object you were measuring lied somewhere between 12 and 13 inches; you could state that the objects length is 12 1/2 inches ± 1/2 inch. The ± 1/2 part is your uncertainty, it means the measurement could be either 1/2 inch longer or shorter than your stated measurement.
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.
No, its more certain than 23.5 mL
When involving in scientific experiments, it is very important to make measurement. In each and every measurement we take, say a length, time, angle etc. we have to use a particular instrument. As every instrument has a least count (also known as the minimal reading), there will be an uncertainty left. As an example, consider a measurement using a vernier caliper as at 10.00 cm, there will be an error of 0.01cm. If we do the same measurement by a meter ruler, there'll be an error of 0.1 cm, or 1 mm. Therefore the uncertainty of a particular measurement is dependent on the instrument it has been taken. As a convention we take the 1/2 of the least count for analog instruments and the least count for digital instruments as its uncertainty.
If the distance is known to perfection, an acceleration is constant, then the absolute error in the calculation of acceleration is 2/t3, where t is the measured time.
The usual measuremnts consist of Units and quantities (how much) More sophisticated measurements should also include some kind of expression for the uncertainty of the measurement.
Some synonyms for uncertainty are doubt or distrust.

Uncertainty or doubt.
unconfidence, uncertainty, doubt
Uncertainty or doubt.
Uncertainty; doubtfulness; doubt.
When giving the result of the measurement, its important to state the precision or estimated uncertainty, in the measurement. The percent uncertainty is simply the radio of the uncertainty to the measured value, multiplied by 100. 4.19m take the last decimal unit, is 9 but with value of 1/100 .01 is the uncertainty Now, .01/4.19 x 100 % = 0.24%
To throw doubt or uncertainty on means that a person is suspicious about or questioning a specific situation. This could say a lot about the person who is throwing doubt on a situation or against another person in that they may be incapable of trusting. On the other hand, the uncertainty may be well founded.
Fear, Uncertainty, Doubt
The length of a meter.
completely: coin is simple probability, quantum uncertainty is based on how increasing accuracy of measurement of one property of a tiny particle reduces the accuracy of measurement of another complementary property of the same particle. No probability there, just measurement limitations.
It is called doubt or uncertainty
