    What is the difference between accuracy and precision?
    Accuracy refers to the consistency of a measured value, while precision refers to the closeness of a measured value to a true or target value.
    Accuracy refers to the highest possible value that can be reached, while precision refers to the lowest possible value that can be reached.
    Accuracy refers to the ability to measure small values, while precision refers to the ability to measure large values.
    Accuracy refers to the closeness of a measured value to a true or target value, while precision refers to the consistency or reproducibility of a measured value.
