Accuracy is a characteristic of the exactness or correctness of an answer. Validity is a characteristic of the answer's appropriateness to the question. For example, if I said, "It is approximately 47 billion, 312 million, 697 inches from New York to Chicago" that may be a very accurate answer to the question "How far is it from New York to Chicago", but it's not very valid - most people don't measure distance between cities in inches.
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
Volume is a measurement of capacity. Dimension is a linear measurement.
Power is a quantity, and the watt is its unit of measurement.
Ampere is a measurement of electrical energy power flow Ohms is the measurement of resistance to flow of energy
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
Imagine a dartboard. An accurate measurement would be analogous to hitting the bulls-eye. While a precise measurement is just the tight clustering of shots.
Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.
The article at the link below should help you get a handle on the subtle differences between accuracy and precision.
The difference between internal and external validity is in their nature. Internal validity indicates if a study depicts relation between two variables. External validity on the other hand generalizes the study of the variables.
accuracy is when you KNOW something and uncertancy is when your not sure
accuracy is the how well it is done. Quality is what something is worth.
accuracy width can be changed but fixed width is a permanent one.
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
Recharge is for extending the validity on the card whereas Top up is when u still have validity but no currency.. top up does not increase your validity whereas recharge does..
Accuracy refers to how close a measurement is to the true value, while reliability refers to how consistent results are when the same measurement is repeated multiple times. In other words, accuracy measures correctness, while reliability measures consistency.
