Journal of Statistics Education: A Sample / Population Size Activity
The author of the article admits having had a difficult time in the past when getting students to understand that samples need to contain a substantial portion of the population. Here, an activity is detailed to bring this important fact...
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.

West Virginia University: Normal Distribution
The history of the normal curve and its use in statistics is presented. An Applet is provided for the user to adjust the left and right edges of the probability and see the effect on the area under the curve.
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: 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.
