In mathematics and statistics, Mean is one method to represent a data set with a single number. When we talk about “Average” we often refer to the “Mean.” The Mean is calculated by diving the sum of data points by that number of data points:
Add Data Points: 4 + 8 + 15 + 16 + 23 + 42 = 108 Sum of 108, Divided by 6 data points = 108/6 = Mean of 18
Mean is easiest to calculate with numbers and quantifiable data, such as your average (mean) nightly hours of sleep, or your mean cost of lunch. For example, the “Average Human” is either calculated from measurements, or it’s a general term people use without accuracy. (more…)
