Covers the variance for a normally distributed random variable.
This video gives more detail about the mathematical principles presented in Variance of Normally Distributed Data.
This video shows how to work step-by-step through one or more of the examples in Variance of Normally Distributed Data.
Examines the statistical concept of standard deviation, which is used to characterize the spread of a distribution. The video also differentiates between sample standard deviations and population standard deviations and introduces the formulas.
This lesson plan covers Calculating the Variance and includes Teaching Tips, Common Errors, Differentiated Instruction, Enrichment, and Problem Solving.
