what do you mean by uncertainty in measurement?

Question

Accepted Answer

Uncertainty in measurement refers to the doubt or range of values that may be associated with a measurement.

It is the range of values within which the true value of a measurement is expected to lie.
It is affected by various factors such as the precision of the measuring instrument, the skill of the operator, and environmental conditions.
It is expressed as a standard deviation or a percentage of the measured value.
It is important to consider uncertainty in measurement when making decisions based on the results of measurements.
For example, if a thermometer has an uncertainty of +/- 0.5 degrees Celsius, a temperature reading of 25 degrees Celsius could actually be anywhere between 24.5 and 25.5 degrees Celsius.
