See the link below. Apparently, descriptive stats just involves the given data. For example, Number 3, "The number of people who are in car accidents each year in Illinois" can be taken at face value. Its purpose is not to infer anything else. It simply describes the situation.
Inferential stats is when the data is used to infer something else in addition to what the stats directly say. For instance, "A poll of 500 people to see who will vote in the upcoming election." We are using the results of the poll to infer what will happen in a future event. Unfortunately, I don’t know enough about the subject to explain all the answers. Edit your post if you have any more questions and I’ll see what I can do. Best wishes.
