Explanation:
The mode is the most common number.
Um = 55
The mean is the sum of the numbers divided by the quantity.
Uavg = (38 + 44 + 45 + 48 + 50 + 55 + 55 + 57 + 58 + 60) / 10
Uavg = 51
The RMS (root mean square) is the square root of the sum of the squares of the numbers divided by the quantity.
Urms = √[(38² + 44² + 45² + 48² + 50² + 55² + 55² + 57² + 58² + 60²) / 10]
Urms = 51.451
