Answer
Answer:
- accurate, but not precise
Explanation:
Step1: Define accuracy and precision
Accuracy is closeness to true - value, precision is closeness of measurements to each other.
Step2: Analyze accuracy
The average volume ($24.94$ mL) is close to the accepted value ($25.00$ mL), so it is accurate.
Step3: Analyze precision
The range is $1.42$ mL, which indicates that the measurements are spread out, so not precise.
