What are importance of statistics?

Answer 1

Statistics is a very effective tool, in which you look at past data from surveys or census', or simply recorded data over a period of time. It is important because using stats you can view past data to help make business decisions, or decisions within any workplace. You can do a statistical test to find out if a new idea or business decision should be considered or rejected. They say "history repeats itself", well by analysing historical data you can find out where past mistakes were made and how to avoid repeating them.
