I'll create math…that's an equity for all. I'll teach math…that's an equity for all. I'll promote math…that's an equity for all. Way too long I've been blind to the barriers I've been building with math. Sorry. I'll continue to do what I do but now strive for an ∃Q∪√-1τy∀

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.

A student in my summer stats class competed in the Strike King Bassmaster College National Championship. I created a graph of the top 50 for them. The data is super interesting. The top 11 are clear outliers and separating themselves from the lower 39.

Update: My student let me know that those people were the only ones that qualified for day 3 - thus the reason for them being outliers. Also, there was a 5 fish limit each day. Here is the top 50 after two days, purple stars qualified for day 3.

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)).

Lots a great stats discussions could arise from this data. Graph link: desmos.com/calculator/ipx14x… p.s. Another push for @Desmos to have a vertical boxplot feature.

Is the @Amplify live chat available to all users or those that are licensed? I clicked on Live Chat, sent to my dashboard and nothing happened. Noticed in their support video that I don't have the Chat icon. Also, their support email refers to live chat.

I don't expect to have Live Chat since I am not a "customer". But being more clear about who this is for would helpful. Lastly, the only place to find support is by clicking on Profile and seeing a help button on the very bottom.

I wonder when the inference for the @desmos calculator will be added to @Amplify classroom. Hopefully, soon.

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 Centering at zero and using standard deviations feels like an outdated way of using tables.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?

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.

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

Trying out the new inference features in @Desmos. Loving the provided visual of the confidence interval and significance test. desmos.com/calculator/rtt6g2…
