In this video, I introduce the idea of conditional probability. I cover the conditional probability formula, work through a few examples, and introduce the definition of independent events.

In this video I explain the formula for calculating the volume of a prism and work through three simple examples.

In this video, I discuss a statistical inference procedure known as a two-proportion z-interval and work through an example of constructing one.

In this video, I discuss a statistical inference procedure called a two-sample t-interval and work through an example of constructing one.

In this video, I discuss the basics of calculating the area of regular polygons, drawing on prior knowledge of calculating the area of a triangle. I don't discuss using trig, special right triangles, or Pythagorean theorem in this video - that'll come in a later video!

In this video, I show a few examples of identifying the basic parts of regular polygons - the center, radius, apothem, and central angle.

In this video, I discuss a thought process to use when choosing a statistical inference procedure. Since chi-squared tests are not covered on the 2020 exam, I do not discuss them in this video.

In this video, I work through an example of the full process of running a one-sample t-test for a population mean.

9.3c Paired t-Test Example

In this video I cover a few examples of calculating the area of a circle.

In this video, I discuss the basics of running a one-sample t-test, such as checking conditions, calculating a test statistic, and calculating a p-value.

In this video, work through an example of running a one-prop z-test and discuss how to write a response that would receive full credit on the AP Stats exam.

In this video, I discuss the basics of the one-prop z-test, including calculating the test statistic and p-value, and condition checks that must be passed.
