in this case, 175+×5010835=×. Even though the average mark is 50%, all the marks are far from 50% so the mean does not tell us much about the list of numbers, here. We need another tool to tell us whether the numbers are close to their mean or far from it. This tool is th...

The arithmetic mean of ungrouped data is calculated using the formula: Mean x̄ = Sum of all observations / Number of observations Example:Compute the arithmetic mean of the first 6odd natural numbers. Solution: The first 6 odd natural numbers: 1, 3, 5, 7, 9, 11 ...
Knowledge of the mean seems to begin and end with an impoverished computational formula. The pedagogical message is clear: Learning a computational formula is a poor substitute for gaining an understanding of the basic underlying concept.doi:10.1007/BF00305621A. Pollatsek...
