Math, Algebra, and Statistics Tutorials
The following mathematical and statistical techniques will be used in various courses throughout your graduate nursing program. If
you haven’t used these techniques recently, we have provided you with links to tutorials provided by Kahn Academy. These tutorials
are very helpful and short. In some cases, we recommend an entire unit on a particular topic. In other cases, we have identified the
most relevant section of the unit. In these cases, you may find it useful to view the entire unit depending on your comfort level with
the topics.

https://www.khanacademy.org/math/arithmetic/absolute-value/abs_value_tutorial/v/absolutevalue-and-number-lines
Entire unit “Intro to percentages” is recommended. The unit begins with:
https://www.khanacademy.org/math/arithmetic/decimals/percent_tutorial/v/describing-themeaning-of-percent
https://www.khanacademy.org/math/arithmetic/exponents-radicals/world-of-exponents/v/level-1exponents
https://www.khanacademy.org/math/arithmetic/exponents-radicals/radicalradicals/v/understanding-square-roots
https://www.khanacademy.org/math/algebra/linear_inequalities/inequalities/v/inequalities-on-anumber-line
https://www.khanacademy.org/math/arithmetic/multiplicationdivision/order_of_operations/v/introduction-to-order-of-operations
Many lessons are available reviewing basic algebraic equations. You can select where to start based
on your level of proficiency. All the relevant lessons can be found at:
https://www.khanacademy.org/math/algebra/solving-linear-equations-and-inequalities
For a basic overview of solving two-variable equations, the following two lessons are recommended:
https://www.khanacademy.org/math/algebra/systems-of-eq-and-ineq/systems-of-eqoverview/v/simple-elimination-practice
https://www.khanacademy.org/math/algebra/systems-of-eq-and-ineq/systems-of-eqoverview/v/practice-using-substitution-for-systems
If more background is needed, the entire unit “Systems of equations and inequalities” can be viewed.
The unit begins with:
https://www.khanacademy.org/math/algebra/systems-of-eq-and-ineq/systems-of-eqoverview/v/trolls--tolls--and-systems-of-equations
The first five lessons in the unit “Graphing solutions to equations” are recommended, but all can be
viewed. The unit begins with:
https://www.khanacademy.org/math/algebra/linear-equations-andinequalitie/graphing_solutions2/v/ordered-pair-solutions-of-equations
https://www.khanacademy.org/math/probability/random-variablestopic/random_variables_prob_dist/v/random-variables
https://www.khanacademy.org/math/probability/random-variablestopic/random_variables_prob_dist/v/discrete-and-continuous-random-variables
https://www.khanacademy.org/math/probability/random-variablestopic/poisson_process/v/poisson-process-1
The entire unit covering the normal distribution and z-score calculations is instructive:
https://www.khanacademy.org/math/probability/statisticsinferential/normal_distribution/v/introduction-to-the-normal-distribution
https://www.khanacademy.org/math/probability/descriptive-statistics/central_tendency/v/statistics-
Central tendency
Variability
Type I & Type II errors
-sample-vs--population-mean
https://www.khanacademy.org/math/probability/descriptive-statistics/central_tendency/v/statisticsintro--mean--median-and-mode
For a basic overview of variability, the following two lessons are recommended:
https://www.khanacademy.org/math/probability/descriptivestatistics/variance_std_deviation/v/sample-variance
https://www.khanacademy.org/math/probability/descriptivestatistics/variance_std_deviation/v/statistics--standard-deviation
If more background is needed, the entire unit “Variance and standard deviation” can be viewed. The
unit begins with:
https://www.khanacademy.org/math/probability/descriptivestatistics/variance_std_deviation/v/variance-of-a-population
https://www.khanacademy.org/math/probability/statistics-inferential/hypothesis-testing/v/type-1errors
No lessons are available for Type II errors, but the threaded discussion on the Type I errors page is
instructive.
