Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

seth heinz (9 months ago)
there can never be 2 middle numbers... according to math antics if you have an even number of numbers and you need to find the middle then find the mode of the two closest numbers to the middle.

My teachers body covers up the whole board and I don’t understand any lesson she teaches because of her “body” not that she’s fat. It’s because she stays in the side and not move.
