AQR Section 17: Mean but Sensitive
The mean is a measure of center and balance point for a distribution. Below is a distribution of 11 data points. Move the blue point to see how the mean responds to changing this single value within the distribution.
Use the New Data Set button, to try this action for several distributions.


Is the mean a resistant measure of center for a distribution?
Is the mean sensitive to a substantial change in the movable blue value?
Guess the Correlation!
Guess the correlation of the random scatter plot!


Bag of Marbles

Normal Curve Demonstration
Drag the sliders to see how changing the mean and standard deviation changes the normal curve.


Playing Card Dealer
Click to get a random hand of cards from a shuffled deck of 52 standard playing cards.


Chaos Game
Creates an image based on the Chaos Game wikipedia Wolfram
It takes a random point in the polygon and then translates it by a fixed fraction of the distance to one of the vertices chosen at random. This iteration is repeated.
Sides gives the number of sides in the polygon
Points is the number of points per iteration
Fraction sets the fraction
Speed adjusts the animation speed
The default settings produce the Sierpinski Triangle

Confidence Intervals
A collection of my applets involving confidence intervals.
-
1. Proportion Confidence Interval
-
2. Mean Confidence Intervals
-
3. Finding P-value for proportion
-
4. Finding P-value for Sample Mean
-
5. Confidence Interval Variation Problems
-
6. Confidence Intervals for the Proportion and the Mean
Proportion Confidence Interval
This applet lets you practice working through examples of finding confidence intervals for proportions.
You can set the sample proportion, the sample size, and the confidence level.
You then should find the critical value, the standard deviation, and the confidence interval.
