Understanding Statistics
Mean
The mean is the average of all numbers. It is calculated by adding all numbers together and then dividing by the count of numbers.
Mean = (Sum of all values) / (Number of values)Median
The median is the middle value when all numbers are sorted in order. For an even count of numbers, it’s the average of the two middle values.
Median = Middle value(s) in sorted dataMode
The mode is the value that appears most frequently in the data set. A data set may have one mode, more than one mode, or no mode at all.
Mode = Most frequently occurring value(s)Range
The range is the difference between the largest and smallest values. It shows how spread out the values in a data set are.
Range = Maximum value - Minimum value
