>>13230743Just take the stats courses at your local university.
I took the intro level and the sampling techniques course.
Stats is just a way to get a good estimate with incomplete information.
For example, you cannot ask everyone in the entire world if they like the color blue (because it takes too much time, and because it costs too much money).
So instead you sample n people where n is a representative sample of N population.
If you just question the smaller group of people, you can get a good estimate (with error less than 5%) and get a good confidence interval on the opinion of the whole population.
Its used for polling national opinion on certain legislation, election polling to see who is likely to win, and other uses.
Stats is not 100% accurate. Even if you're 95% confident that your hypothesis is correct, there will always be a 1/20 chance that you're wrong.
Just make sure that you always write your conclusion as a sentence. It's really important to state your answer as a word sentence in any statistics class.
