Ck 12: Statistics: Normal Distributions
[Free Registration/Login may be required to access all resource tools.] Determine if a data set approximates a normal distribution.
Texas Instruments
Texas Instruments: The Normal Distribution
Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.

Ck 12: Statistics: Applications of Normal Distributions
[Free Registration/Login may be required to access all resource tools.] This Concept introduces students to applications of the Normal Distribution.
Texas Instruments
Texas Instruments: The Normal Distribution
In this activity, students will apply the normal density function, normal cumulative distribution function, and inverse normal cumulative function to analyze a population with a normal distribution.
Texas Instruments
Texas Instruments: Normal Distribution
This set contains statistics questions regarding the normal curve, its distribution, and its applications. The student, using the correct calculation, transitions between observed x-values, standard z-scores, and normal curve areas.
Texas Instruments
Texas Instruments: Special Cases of Normally Distributed Data
Students perform single and two-sample t procedures to investigate special cases of normally distributed data. They explore inference for a least-square regression line, including the confidence interval.
