how would I determine whether 'STATUS' is "1 standard deviation" away from the other value cardinality values? 

Find the mean (m) and standard deviation (s) over all the "value_card" values from that column (or the combined-over-single-row "value_card" values). The distance of "STATUS"'s "value_card" from another entry's value card, say 'ACTIVE' is their absolute difference. The distance in terms of standard deviations is the previous value divided by the standard deviation. That will tell you how many standard deviations apart they are.

But this gets less and less trustworthy as the number of value_cards gets smaller. For example, this online outlier tool sees 1 outlier but it is not what we think it is!!! https://www.graphpad.com/quickcalcs/grubbs2/ (got it from How to best eliminate values in a list that are outliers which maybe relevant to your problem)
