To illustrate differences among types of information, we might base the conclusion that the day was hot on data from an instrument that records the room temperature (numerical and objective), a record of the atmospheric temperature as written down by an observer checking a thermometer (numerical and relatively nonsubjective), a survey asking people how hot they felt (nonnumerical and subjective), and a thick description of what clothes people were wearing, how much they perspired or shivered, whether they turned up the furnace or the air conditioner, and how much energy they seemed to have for work (nonnumerical and judgmental).
We might use qualitative information to judge things like temperature.
