Which of the following best describes the term "exclusive range"?

The term "exclusive range" refers specifically to the difference between the highest score and the lowest score in a dataset. This concept is crucial in statistics as it provides a measure of the spread or dispersion of the data points. By subtracting the lowest value from the highest value, you obtain the exclusive range, which helps to understand the extent of variability within the data.

The exclusive range does not include the actual values at both extremes (i.e., it is computed based solely on the numerical values themselves). This term is particularly useful in various fields of research and program evaluation where understanding variability is essential for data interpretation and analysis.

In contrast, other options presented do not correctly reflect the definition of the exclusive range. The difference between the mean and median is a measure of skewness, and the sum of all scores refers to a total rather than a range. The average score represents a central tendency and does not provide information about the spread of the data.
