gnomes: Gnomes mushroom insulation cost-effectiveness data

Description

The gnomes dataset consists of 300 observations of gnomes that had their housing unit (i.e., their mushroom) insulated against cold and humidity. The insulation was done by the most skilled insulation animals in the forest: squirrels (Sciurus vulgaris).They either used the common insulation technique consisting of leafs of the common beech tree (Fagus sylvatica) or an experimental form of insulation using leafs of the less common (and thus, more expensive) sessile oak tree (Quercus petraea). For the year before insulation and the year after insulation, the gnomes filled out the Gnomes' Humidity and Thermal Satisfaction scale (Gnomes' HATS), a well-validated questionnaire that rates mushroom insulation satisfaction w.r.t. humidity and temperature on a scale of 0 to 50. Differences between pre and post measurement were calculated on a higher-is-better basis.

The squirrels were paid in acorns.
