In a relative frequency distribution, "relative" specifically refers to the proportion of the data values that fall into each class compared to the entire data set. This is a crucial concept in statistics, as it allows for the understanding of how significant each category is within the overall context of the data being analyzed.

When creating a relative frequency distribution, each frequency (the count of occurrences in a class) is divided by the total number of data points, resulting in a proportion that illustrates the relative standing of each class. This means that option B, which mentions proportion of the data values, accurately captures the essence of what "relative" signifies in this context.

The size of the data set, as indicated in option C, does not directly address what is meant by "relative" in a frequency distribution. The focus is on the relationship of each class frequency to the whole data set rather than the overall size of the data set itself. Thus, understanding "relative" hinges on comprehension of proportions, making B the correct understanding in this instance.
