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 to get more information than just quantitative .
