Description

Capturing Props with CIs

Demonstration from Statistics with 30 cases, 1 attribute. Useful for Activity, Demonstration

Shows a polling sample drawn from a population whose probability of success is given by a slider. Measures are collected using this sample to show the confidence intervals over many trials and the ones that do and don't capture the true proportion.

ConfidenceIntervalDemo

Demonstration from Statistics with function plot. Useful for Activity, Demonstration

Helps answer the question, why does the sampling distribution centered on the sample proportion help you determine the upper and lower bounds?

ConfidenceIntervals

Simulation from Statistics with 10 cases, 1 attribute. Useful for Activity, Demonstration

Shows “capturing” of true mean by confidence intervals.

ConfIntervalDemoBinom

Demonstration from Statistics with function plot. Useful for Activity, Demonstration

Helps show the reasoning for getting from a single sample to an upper and lower confidence bounds for the population proportion.

EstProportionAlgorithm

Demonstration from Statistics with 5 cases, 2 attributes. Useful for Demonstration

Explains Fathom’s algorithm for computing a confidence interval from a binomial distribution.
