I think the role statistics have in our society is to inform people on the subject a given topic, and possibly influence people to change their opinions on the given topic.
I learned more about the importance of statistics in our society such as general information for safety and everyday life. For example, the percentage of people who survive car crashes when wearing seat belts to the percentage who survive that don’t.
The problems with statistics are that they can be merely made up, there can be bad sampling, unfair poll questions, and misleading statistics.
