Trying out the new inference features in Desmos. Loving the provided visual of the confidence interval and significance test. desmos.com/calculator/rtt…

Another push for @desmosclassroom to add the desmos 3D and geometry as a full screen option to the Activity Builder. Thanks! desmos.com/3d/zqcdfbcpoy

What if Desmos had the feature to export a confidence interval diagram? I would like to see a diagram of the distribution with 95% shaded. Maybe clicking on the distribution curve could bring up the lower and upper bounds, like how the peak of the distribution is shown.

What is your style for a t or z test? I like to show the distribution centered at the null. Centering at zero and using standard deviations feels like an outdated way of using tables. But maybe I am missing some thing? Which diagram would you want @desmos to show?

Had students pick a song and use the lyric words lengths to create a game. I noticed that a spinner can really support the idea a discrete probability distribution. Before I would only show the graph (x, P(x)).

I noticed in my Classroom Amplify Stream that I have few activities that say archived, when they are not. If I click on View Work, then it shows an empty dashboard. But if go directly to the activity, then choose dashboard, all of the student work is there. Strange.
