know number of data-missing row when making a summary table
Hi all JMP experts, I'm making a summary table from a raw data table - taking median by group names defined in column "purpose," e.g. a group is named "BSL."The summary table shows that there are totally 744 rows of group "BSL" that are used for summary-extraction, but is there a way to know within the 744 data rows, how many rows contain/doesn't contain(i.e. missing) numbers?
