The three averages and range
The following are different types of averages:
Mode – is the most common
Mean – if the sum of values ÷ number of values
Median – middle value
Range – this is not an average, but spreads out data from the largest to the smallest value.
The mode as mentioned above is the most common item which occurs in a data set. The modal is also used to describe the mode.
For example: in the following set of data, 11 is the mode:
1, 45, 11, 33, 12, 65, 32, 11, 23, 11, 14, 11, 11, 11, 24.
When the mode is not appropriate
In situations where data is heavily skewed (being heavily weighted towards on data set), the mode may not be appropriate because the representation of the data is not provided fairly.
