Detailed explanation-1: -The correct answer is Option d 20.2 ml, 20.5 me, 20.3m6, 20.1 ml. Accuracy: Accuracy of measurement is the precise value of that object with the least or no difference from the actual value.
Detailed explanation-2: -Q2) The volume of a liquid is 20.5 mL. Which of the following sets of measurement represents the value with good accuracy? Answer: The set 20.2 mL, 20.5 mL, 20.3 mL, 20.1 mL represents the value with good accuracy.
Detailed explanation-3: -If you want to tell which set of data is more precise, find the range (the difference between the highest and lowest scores). For example, let’s say you had the following two sets of data: Sample A: 32.56, 32.55, 32.48, 32.49, 32.48.
Detailed explanation-4: -The degree of closeness to the exact value is the accuracy of measurement or approximation. Error: The difference between the measurement and the exact value is the error. Resolution of an instrument is the smallest increment an instrument can detect and display i.e. hundredths, thousandths, millionths.
Detailed explanation-5: -Accuracy is defined as the value or how much our calculated value is close to the true value of that particular calculation. While precision refers to the values or how close our calculated values to each other.
