Tag me in finished polls. At this moment, I can only do binary (yes or no, this or that, etc.) or quantitative (hours of sleep, sibling count, etc.). HOWEVER!!! If a poll has TWO (and only two) variables, for instance "Are you an iPhone user, and do you have TikTok?" or "Are you over or under 18, and how many blankets do you own?", I can calculate a confidence interval for the difference between proportions/means of both parties! This is purely for fun and analysis.

UPDATE: I can now run chi-square tests for independence! This means I can calculate if two variables (for instance, gender & hours of sleep, age group and any yes/no option, etc.) are associated.

Also, please no N$FW polls. I will not analyze those.

This short animated video gives an explanation of the concept of confidence intervals including estimates with helpful diagrams and examples.

A small sample of ideas - just some of the answers I've tried to provide to questions in the NZ stats and maths teacher Facebook groups recently.

While I continue to decide whether to quit Facebook, I’ve been trying to keep on top of my admin responsibilities for the Stats Teachers NZ Facebook group while keeping an eye on any stats-related posts on the NZ Maths teachers Facebook group. Since not everyone is on Facebook, I thought I’d do a quick post sharing some of the ideas for teaching stats I’ve recently shared within these groups.
