Sampling Distributions & Standard Error
Explore how sampling distributions behave as the sample size $n$ changes.
Open tool →Confidence Interval Explorer
Simulate repeated $t$-intervals and see how often they capture the true mean.
Open tool →t-Distribution Explorer
Compute p-values, critical t-values, and inspect a t-table for common significance levels.
Open tool →F-Distribution Explorer
Explore F-distribution tails, critical values, and variance-ratio intuition for the F-test.
Open tool →F-Distribution From Repeated Sampling
Repeatedly sample two normal populations to see how the F ratio distribution forms.
Open tool →Simple Linear Regression Explorer
See how sampling, fitted lines, residuals, and MSE behave in a simple linear regression.
Open tool →t-Test Hypothesis Test Visualizer
Locate your one-sample t-value on the t-distribution and see the two-tail p-value.
