Purpose of Statistics

Everywhere you go, everything you see, statistics is all around. I for one, did not realize how important and relevant statistics was in our everyday lives until taking this course. Everything is run by statistics; the kind of coffee available in Dunkin’ Donuts, the flavors of ice cream at Dairy Queen, and even the clothes we buy in stores.

I actually play video games competitively and travel to competitions to win money. I pick and choose my teammates almost solely based on the statistics that are on the leaderboards. If they have a combination of a high-win loss ratio, high accuracy, and a high points per-match; then they must be a good addition to the team.

An example would be if a group of researchers wanted to find out between two mayoral candidates who is more liked. They would have to target all of the voters in the city, then get maybe around 1,000 of them and look at the polls. They might even design a systematic sample from a list of all of the voters, grab any name at random, and then get in touch with every 200th voter they come across. This would give them a nice random sample and a more in depth look at who was going to win.
