Q.State the relationship connecting the median, quartiles, deciles and percentiles of the same distribution.

Several partition values must coincide exactly because their underlying fractions of the series are equal.

Because every partition value simply locates a stated FRACTION of the ordered series, values sharing the identical fraction must be identical:

This relationship holds for EVERY dataset, not just specific examples — it follows purely from the arithmetic of the position fractions, not from any property of a particular distribution's shape.

Stating the relationship as approximate ('Q2 is close to the median') rather than exact — unlike the empirical mean-median-mode relationship from the earlier chapter, the partition-value relationships here are exact identities, true for every dataset without exception.
