frequency distribution is the median of the grouped data. The centre number in the set of data, known as the median, is what divides the data set’s upper and lower halves. Since the data is divided into class intervals, the middle value is unknown when calculating the median of groupe...

We describe the joint distribution of counts in such a table by the term empirical bivariate quantile-partitioned (EBQP) distribution. Blomqvist (1950, Annals of Mathematical Statistics 21, 539-600) gave an asymptotic EBQP theory for bivariate data partitioned by the sample medians. We ...
