The question asks for the term that describes "the ratio between the sum of the data divided by the total number of data".

Mathematically, this ratio is expressed as:

$$ \text{Value} = \frac{\sum_{i=1}^{n} x_i}{n} $$

where \(\sum_{i=1}^{n} x_i\) represents the sum of all data values, and \(n\) represents the total number of data points.

Evaluate the given options

• median: The middle value of a sorted data set. It separates the higher half from the lower half of a data sample.
• mean: The arithmetic average of a set of values, calculated by summing the values and dividing by their count.

Therefore, the correct term is the mean.
