What does 'range' refer to in a dataset?

In statistical analysis, 'range' specifically refers to the difference between the highest and lowest values in a dataset. This measure provides a quick understanding of the spread or dispersion within the data. For instance, if the highest value in a dataset is 50 and the lowest is 10, the range would be 50 - 10, which equals 40. This indicates how much variability exists in the data.

The other options pertain to different statistical concepts: the average or mean involves calculating the sum of all values and dividing by the number of values, the count refers to how many data points are present in the dataset, and the sum simply adds together all the individual values. Each of these concepts serves a distinct purpose in data analysis but does not define the term 'range.'
