Joshua wants to convince his parents that he is old enough to have a smartphone. he thinks the fact that most teenagers at his high school have a smartphone would be convincing. which way should joshua collect data to best support his argument?

He should collect all the good reasons why having a smart phone can be useful . On a piece a paper her can write all the good reasons . Which can be making an emergency call if anything , calling the police or using the internet to google important questions

He should collect data with a graph

hope this helps
