The range can be calculated from the given information because it is the difference between the highest and lowest values in a data set, which are provided (0.333 and 0.224). Variance and standard deviation require more detailed data than just the high, low, and average values. Percentiles also cannot be determined without more specific data points or a distribution curve.
