How do you choose the type of graph to use? like line graph or bar graph

Bar is to show more typical data like icecream flavors, and line is to show progression like how much a flower has grown over time.

It depends on the question and information given. a line graph is usually used to compare information like from one month to the next. bar graph is also used to compare but it is more likely to be used with objects or for example who liked cats vs. dogs. Hope this helped!

The range would be 13 because you’re finding the difference
