Why is one answer not a precise answer?
Explain your answers completely. Just one answer could not be considered precise because the definition of precision clearly states that precision is the agreement among a set of measurements made of the same quantity in the same way. This means that in order for a recording to be precise there must be several measurements.
What is the importance of accuracy in chemistry?
The study of chemistry starts with understanding accuracy and precision . Accuracy involves a true value. Being accurate involves no estimated figures but those instead that are not questionable. By using accuracy in chemistry, the results will have less of a chance of producing error.
How is the accuracy of an instrument determined?
Such type of accuracy of the instruments is determined by identifying the measured value regarding their true value. The accuracy of the instruments is neglected up to ±0.5 percent from the true value. The closeness of two or more measurements to each other is known as the precision of a substance.
What is the difference between precision and accuracy?
The meaning of accuracy is the extent to which a given measurement agrees with the standard value for that measurement. The meaning of precision is the degree to which the correctness of a quantity is articulated.
