What is an exit poll?
An election exit poll is a poll of voters taken immediately after they have exited the polling stations. Unlike an opinion poll, which asks whom the voter plans to vote for or some similar formulation, an exit poll asks whom the voter actually voted for. A similar poll conducted before actual voters have voted is called an entrance poll. Pollsters - usually private companies working for newspapers or broadcasters - conduct exit polls to gain an early indication as to how an election has turned out, since in many elections the actual result may take hours or even days to count. Typically a question that is asked is... "who did you vote for?"
Is accuracy a measure of how close an answer is to the actual or expected value?
Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy.
What is aceptable drawing accuracy standard?
The answer depends on the purpose. For example, the accuracy required from an engineering drawing is much greater than a child's drawing of his house.

the answer is Whether the sample was selected from the population by a random method
How close a measurement is to the true value is?
Accuracy
What does accuracy of a DAC mean?
Deviation of real DAC output votlage from expected DAC output voltage for particular code written to the DAC. Accuracy is mostly expressed in LSB.
Why is density expressed in two significant figures?
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.
How can you calculate the accuracy of an analytical method?
To calculate the accuracy of an analytical method, you can compare the results obtained from the method to a known standard or reference value. This can be done by performing samples with known concentrations or properties and then measuring the accuracy by determining the percentage error between the measured values and the known values. The accuracy can be expressed as a percentage or a confidence interval.
