For class pages, LMS, and blogs

Embed statistics demos

One iframe tag adds a live, draggable statistics demo to Google Sites, Canvas, Schoology, WordPress or anything else that accepts HTML. Free, no login for your students. Pick a widget page rather than copying every snippet from this catalog.

8 interactives are ready. StatsLearn is interactives first: start at widgets, with the sandbox as the default. Steps for class pages and LMS hosts, and a page written for AI assistants. The mean vs median guide is the identity in words.

Every interactive

Open a widget page for the iframe. This page exists for the embed-graphs query. The front door is /widgets.

• Which test chooserAnswer two or three questions about your data and design, and the right procedure falls out with the calculator to run it.
• Descriptive statistics calculatorPaste a column of numbers and get every summary statistic at once, with the boxplot and histogram drawn on a shared scale.
• Descriptive statistics sandboxDrag data points on a dotplot and watch the mean chase outliers while the median holds still. The boxplot, SD, and IQR update live.
• Sampling distribution and CLTPick a lumpy parent population, slide the sample size, draw thousands of samples, and watch the distribution of sample means turn normal and narrow by root n.
• Normal curve explorerDrag the boundaries on a normal curve to shade a tail or a middle band, and read the probability, the z-scores, and the percentiles as you go. Lock the z-scores and the area holds while the mean and SD move.
• CI coverage simulatorDraw hundreds of samples, build a confidence interval from each, and count how many actually capture the true parameter. What 95 percent confidence means, as a tally rather than a sentence.
• Type I, Type II, and powerSlide the true parameter, the sample size, and alpha, and watch the two error regions trade off against each other. Power is the area you are trying to grow, and it is drawn.
• Regression influential pointDrag one high-leverage point and watch the least-squares line, r, and the residual plot swing. Influence, made physical.
