While performing an experiment involving a reaction between two chemicals, the scientist observes that the reaction container has become warm. the observation is an example of: a- qualitative data b- quantitative data c- both qualitative and quantitative data d- the observation is not considered data

The correct answer is A. Qualitative data

Explanation:

In research and therefore in observation, qualitative data is the type of data that describes non-numerical information or data, for example in reactions qualitative data can be physical properties or changes in color. This is the opposite of quantitative data that focuses on numerical information such as the amount of a substance. This means observing a reaction container has become warm is an example of qualitative data because the scientist is describing qualities in reaction but not quantities or numerical information.
