Hoeing to ploughing is a discontinuous function. Either you scratch the ground with your hoe or you plough it. There is no middle ground where your hoe gradually gets heavier and turn into a plough.
- zeteo 14y agoAgain, 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 14y 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.
