Explanation / Answer

7. Percentage error ca be calculated from the following formulae

Percentage error = [(Calculated volume of water - Measured volume of water) / (Measured volume of water)]x100

Measurement-1:

Percentage error = [(Calculated volume of water - Measured volume of water) / (Measured volume of water)]x100

= [(10.24 - 10) / 10]x100 = (0.24 / 10)x100 = 2.4%

Measurement-2:

Percentage error = [(Calculated volume of water - Measured volume of water) / (Measured volume of water)]x100

= [(10.14 - 10) / 10]x100 = (0.14 / 10)x100 = 1.4%

Measurement-3:

Percentage error = [(Calculated volume of water - Measured volume of water) / (Measured volume of water)]x100

= [(10.53 - 10) / 10]x100 = (0.53 / 10)x100 = 5.3%

Measurement-2:

Percentage error = [(Calculated volume of water - Measured volume of water) / (Measured volume of water)]x100

= [(10.26 - 10) / 10]x100 = (0.26 / 10)x100 = 2.6%

Measurement-5:

Percentage error = [(Calculated volume of water - Measured volume of water) / (Measured volume of water)]x100

= [(10.28 - 10) / 10]x100 = (0.28 / 10)x100 = 2.8%

8. Average of the percentage error for the first three measurements = (2.4%+1.4%+5.3%) / 3 = 9.1% / 3 = 3.03 %

Average of the percentage error for all the measurements = (2.4%+1.4%+5.3%+2.6%+2.8%) / 5

= 14.5% / 3 = 2.9 %

As we increase the number of measurements, the percentage error improves and the measurement approahes the most accurate one.
