If you’re looking for help with probability and statistics topics, you’re in the right place. We have a comprehensive database of articles and hundreds of statistics video tutorials covering all the material you’re likely to find in an AP statistics, elementary statistics or college statistics class.

**Statistics How To** has over a thousand articles and hundreds of those include short, how-to videos that you can also find on our YouTube Channel.

**What is Probability and Statistics?**

Probability and Statistics usually refers to an introductory course in probability and statistics.

The “probability” part of the class includes calculating probabilities for events happening. While it’s usual for the class to include basic scenarios like playing cards and dice rolling at first, these basic tools are used later in the class to find more complex probabilities, like the probability of contracting a certain disease.

The “statistics” part of probability and statistics includes a wide variety of methods to find actual statistics, which are numbers you can use to generalize about a population.

Statistics How To example: you could calculate the height of all your male classmates and find the mean height to be 5’9″ — this is a statistic. But then you could take that statistic and say “I think the **average** height of an American male is 5’9″ “. How accurate your guess is depends on many factors, including how many men you measured and how many men are in the entire population. Statistics are useful because we often don’t have the resources to measure, survey or poll every member of a population, so instead we take a sample (a small amount).

**Intro To Statistics Video Tutorials**

Many people find statistical analysis puzzling. Why? Because it demands new ways of thinking. And how do you fathom these new ways of thinking? In order to fathom statistical analysis properly, you need to understand a number of its **key foundations**. Reading textbooks doesnâ€™t work because textbooks donâ€™t focus on foundations, and they cover so much ground in so much detail that you are bound to lose sight of the forest for the trees.

Even if youâ€™ve taken statistics courses in the past, and even if you know the mechanics of performing statistical analysis, youâ€™ll benefit from understanding these foundations. On **Statistics How To** you will find hundreds of statistics video tutorials for elementary statistics, probability, AP and advanced statistics topics.
