Answer
(total potential difference / total number of readings) = (0.16V + 0.17V + 0.15V) / 3 = 0.16V
Explanation
Mean potential difference can be calculated by adding up all the measurements and then dividing by the number of measurements. In this question, there are three readings: 0.16V, 0.17V, and 0.15V.
