This lesson presents an example of dependent probability. [Probability playlist: Lesson 11 of 29]

This lesson begins a six part series of basic probabiltiy using module examples. [Probability playlist: Lesson 4 of 29]

This lesson demonstrates probability using combinations and shows the probability of getting exatly 3 heads in 8 flips of a fair coin. [Probability playlist: Lesson 14 of 29]

This lesson is another demonstration of probability and combinations to determine the probability of making at least 3 out of 5 basketball free throws. [Probability playlist: Lesson 15 of 29]

This lesson uses playing cards and Venn Diagrams to explain the idea of probability [Probability playlist: Lesson 2 of 29]

Proof: Any subspace basis has same number of elements. Created by Sal Khan.

Sal solves a linear system with 3 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form. Gaussian Elimination is the method, reduced row echelon is just the final result.

Determining whether 3 vectors are linearly independent and/or span R3. Created by Sal Khan.

This 10-minute video lesson explains box and whisker plots. [Statistics playlist: Lesson 9 of 85]

This 8-minute video lesson takes problems from CK12.org to discuss using the Empirical Rule with a standard normal distribution. [Statistics playlist: Lesson 33 of 85]

This 6-minute video lesson uses problems from CK12.org to provide more Empirical Rule and Z-score practice. [Statistics playlist: Lesson 34 of 85]

This 10-minute video lesson takes some problems from CK12.org and uses the empirical rule (or 68-95-99.7 rule) to estimate probabilities for normal distributions. [Statistics playlist: Lesson 32 of 85]

This 11-minute video lesson takes some problems from CK12.org and discusses of how "normal" a distribution might be. [Statistics playlist: Lesson 30 of 85]

This 10-minute video lesson shows how to calculate R-squared to see how well a regression line fits the data. [Statistics playlist: Lesson 70 of 85]
