    Answer:

    Mean

    Explanation:

    The mean of a series of measurements is calculated when all the measurements are added up and then divided by the number of measurements taken, as follows:

    • Sum of Measurements = 20.73 + 20.76 + 20.68 + 20.75 = 82.92

    As there are 4 measurements, the mean is:

    • Mean = 82.92 / 4 = 20.73
