Description

BootstrapMedianEstimate
|
Demonstration from Statistics with 500 cases, 11 attribute. Useful for Activity, Demonstration
|
Census data for 500 people, used to demonstrate estimation of the median income - best guess and an interval.
|
CentralLimitTheorem
|
Demonstration from Statistics with 10 cases, 1 attribute. Useful for Activity, Demonstration
|
Provides a population that is non-normal and the ability to sample from it and observe the sampling distribution’s approach to normal.
|
CollectingMeasuresDemo
|
Demonstration from Statistics with 10 cases, 1 attribute. Useful for Learning Fathom
|
Demonstration of how to use a measures collection to collect values while a slider value is changing.
|
PoissonDistSampleSizes
|
Demonstration from Statistics with 11 cases, 0 attributes. Useful for Learning Fathom
|
Shows how one can draw samples of randomly determined sizes. In this case, the sample sizes are chosen from a Poisson distribution with mean lambda.
|
Polling Simulation
|
Demonstration from Statistics with 20 cases, 1 attribute. Useful for Demonstration
|
Illustrates how repeatedly taking a poll from a population will build up a distribution of proportions that closely matches the prediction made using binomial probabilities.
|
RandomSampleSize
|
Demonstration from Statistics with 1 case, 1 attribute. Useful for Demonstration
|
Shows relationship between sample size and standard deviation of samples.
|
Sample Until_withSlider
|
Demonstration from Statistics with 1 case with 1 attribute. Useful for Learning Fathom
|
Shows how to randomly choose a sample size.
|
SampleSizes with slider
|
Demonstration from Statistics with 1 case with 1 attribute. Useful for Learning Fathom
|
Provides a method for controlling sample size with a slider.
|
SampleSizes
|
Demonstration from Statistics with 1400 cases, 2 attributes. Useful for Learning Fathom
|
Shows the distribution of values drawn from a population for three slider-controlled sample sizes.
|
Small Sample
|
Simulation from Statistics with 3 cases, 1 attribute. Useful for Activity, Demonstration
|
Compares the distribution of means with the distribution of t-values for a small sample.
|
Stratified sampling
|
Simulation from Statistics with 1000 cases, 2 attributes. Useful for Learning Fathom
|
Demonstrates one way to do stratified sampling, using an “over-sampling” technique.
|
Stratified vs Simple
|
Simulation from Statistics with 100 cases, 10 attributes. Useful for Demonstration
|
Compares the sampling distribution of means using simple random sampling compared with that of stratified sampling.
|
StratifiedV2
|
Simulation from Statistics with 100 cases, 2 attributes. Useful for Demonstration
|
Compares the sampling distribution of means using simple random sampling compared with that of stratified sampling.
|
TorZ
|
Simulation from Statistics with 1 case, 1 attribute. Useful for Demonstration
|
Working with samples of size 3, shows that the sampling distribution of the t-statistic is a t-distribution, not a normal distribution.
