Again, weight of farm tools is a naturally continuous variable. There are heavy hoes, light plows and lots of ground in between [1] [2]. Transforming weight into a binary variable with an arbitrary separation point is not sound statistical practice.

- hackinthebochs 13y ago>Transforming weight into a binary variable with an arbitrary separation point is not sound statistical practice But the separation is not arbitrary. "Light enough to wield by women" is the important statistic here, so the value in question is binary by nature. Weight in isolation simply isn't what is being considered here.
- s_baby 13y agoThe effectiveness of a tool as a function of its weight is not necessarily linear either.
