As the name says the goal of the descriptive investigation is to describe. 
This type of investigation has no hypothesis, but only a question. With this type of investigation Tyler will be able to observe all types of insects and study the insects in many various aspects and provides a bigger overview, because it uses both quantitative and qualitative data.
